Sonicomi is a very expansive game. It features 18 conclusive endings, an abundance of outfits and a really interesting game-play mechanic. So this game has a lot of replay value. Completing the game really requires lots of effort.
I wrote this guide to cover all Achievements of the game. I maybe quite late to the party, as there are several guides about getting all the Good Endings. However, this is a 100% Achievement Guide, so way way way more complicated. Hopefully, I can help future perfectionist like me.
Also, a quick warning: There are four Achievements that are exceptionally arduous and painful to get: Doomed Wanderer, Clothing Master, Accessory Master and True Sonicomi Master. There will be sections dedicated just for them, and their name will appear on that section's title. They deserve it.

TIPS:
These tips that I have concluded will make your life easier when playing the game. You may not understand them if you have just barely advanced the game. However, once you know what you are doing, these Tips should help a lot.

1. These following tips are related to game-play in general, so you should at least play the first stage to get the general ideal how the game-play works. I decided to group them all in one.

• In order to get a high score, always change position when the Action Bar is full. The Enthusiasm Gauge can be charged by both Talking to Sonico and getting Perfect or Great at the circles. However, Talking will only fill very little Enthusiasm (like up to 20%), and if Sonico stays at the same position for a very long time, getting Perfect or Great will not fill the Enthusiasm Gauge quickly anymore.
  
• Use Talking when the Enthusiasm Gauge is completely filled to gain Enthusiasm Level. Maximum Enthusiasm Level is 3, and higher Enthusiasm Level gives more circles and more scores.
  
• Getting Perfect earns twice more score than Great and four times more score than Good.

2. Your clothes decide your position, or how you move to be more precise, on the grid.
This is a quite obvious thing, but since it is also very important, I will put it here. Basically, when you put on certain outfit, you will move a bit on the grid, which determines the game route and Endings. So check your current position before shooting, and if it is not the direction that you want, change to another outfit. Just remember to pay attention to the client's request percentage though.

3. Once you completed a client's request, you can use the Skip Shoot function.
Say if you want to move left, but the outfits that requires sufficient client's satisfaction will end up moving you right, you can just equip the outfit, and complete the shoot. Then reload the save at the beginning of that shoot, change to another outfit that fits the direction that you desire, then Skip Shoot. You need to complete a client's request at least once to make the Skip button available.

4. You can save outfits set to equip it later.
For some reason, exactly nothing mentioned this in the Tutorial. It will come very handy later.






It is the headphone icon.

5. Hard Mode is very important.
In case you don't do well with Hard Mode, spend sometime practicing.

6. Save and Data folder location:
C:\Users\[Your User Account Name]\AppData\Roaming\Nitroplus\SONICOMI_en
This will come in handy in some case, like when you want to clear the save files for example. If you want to delete save files, just delete the numbered folders. SYSDATA and system.dat are the progress and config files, so unless you know what you are doing, better leave them untouched.

7. Even Hall is a great shooting location.
For some reason, the Enthusiasm Gauge charges really fast, so more circle, more scores and more Sonicoin. It is unlocked when you begin any shoot in Episode 7 of the most Niche route (Endings 13-15). More information about route or branch is available in the Ending Achievements part 1 section.

8. Complete the game once to unlock Ouka shop, where you need the two really important items for completing the game: Position Chart and Outfits Data.









They both costs 1000 Sonicoins each. The Position Chart shows the position of the Endings on the grid and which Ending is missing. The Outfit Data shows how the selected outfit will affect your position in the grid, and how is that outfit compared to the client's request.






That should conclude the important tips. More information about specific Achievements is available below.

These Achievements are pretty self-explanatory and relatively easy to get. If you participate in the game long enough, you will eventually get these Achievements without really noticing or trying a lot.


Wild Photographer
Photograph a sub-target.



When you participate in shooting Sonicomi, depending on your shooting location, different animals may appear randomly. Take a picture of an animal to get this Achievement.



King of Beasts
Photograph 100 sub-targets.



Basically doing the previous Achievement 99 more times.If you want to get this Achievement as fast as possible, I suggest taking picture at the Beach. Here, birds may fly in huge flock, not to mention the dolphin.



















Super Combo
Get a combo score of 100.



It is a relatively easy Achievement. Bad and Poor will break combo, so do not get those. Also, Easy Mode will spawn the least circles each shoot, so you might want to do these on Normal or Hard difficulty.




Ultra Combo
Get a combo score of 200.


Now this one is a bit tricky. On Normal difficulty, there will be barely enough circles to get this Achievements. So you should do this Achievement on Hard mode, with a client that only requires one shoot, as clients who require two or three shoots will have less time available for each shoot. Also, shooting at Event Hall will result in more circles.




Nervous Date
Go on a first date with Sonico.


The first date happens on Episode 4. It will always trigger, so there is not much to talk about.




Great Shoot!
Get and SS ranking on a photo shoot.


I think getting an SS raking is fairly easy, especially with the first shoot in Episode 0. If you could not get it, simply practice more. However, keeping mind that playing on Easy will never award an SS rank.



Rookie Photographer
Complete 10 photo shoots.



Finish 10 shooting requests to get this Achievement.



Passionate Photographer
Complete 50 photo shoots.



Well, it won't get any more self-explanatory.



Veteran Photographer
Complete 100 photo shoots.



It will take some time, but as you keep playing, you will get this Achievement eventually.



Easy Mode
Beat the game on Easy difficulty.



Playing on Easy Mode and get to an Ending (excluding Bad End of course, and probably Ending 18) to obtain this Achievement. Also, this Achievement will not unlock even if you complete the game on Normal or Hard Mode, so you need a separate play-through for this, which is quite annoying.



Normal Mode
Beat the game on Normal difficulty.



Should be similar to Easy Mode, albeit on Normal difficulty.



Hard Mode
Beat the game on Hard difficulty.



Hard Mode will unlock after you beat the game on Normal difficulty. So, beat it again on Hard Mode.



Dream Fulfilled
Beat the bonus stage.



When you finish the last take from a client that requires multiple takes, while Sonico is having full Enthusiasm Gauge and Enthusiasm Level 3 (max), you will enter the Bonus Stage.
All you have to do in the Bonus Stage is to build as much combo and gain as much extra scores as possible. Getting Bad or Poor will not break combo or anything quite negative, so you cannot fail this stage anyway. Finish it to get the Achievement.

So in this part, I will be talking about the routes/branches strucutre of this game. While it is not fully related to every Ending Achievements, I think it is still important to understand how this game branching out, for the sake of completing other Achievements.

Episode 0
In this Episode, you will have the first shoot. The client will have 100% satisfaction score with this shoot, no matter what outfits you put in. So if you have already planned a certain direction or Ending that you want, this shoot is a nice first boost.

Episode 1
There is a choice with 3 options here that will affect Sonico location, aka move her, on the grid. However, the impact of the choice is quite minimal, I think. So just focusing on the outfits is a better option, you don't need to mind the choice.

Episode 2
There will also be a choice with 3 options, quite similar to Episode 1, so I guess there is not much to talk about.

Episode 3
This is where things start to separate. Starting from this point, every shoot will have more than one take, meaning you can push Sonicomi further in the direction you want. On top of that, the position of Sonico on the grid right after Episode 3 shoot will decide the scene of Episode 5 (and the Second Date if it occurs) later.
There are three possible Episode 5 scenes, determined by Sonico's position, separated by three regions of color below. Again, the position is determined, aka Episode 5 is locked, right after Episode 3 shoot, so keep that in mind.





























Episode 4
Episode 4 is the first date. Use it to increase Sonico's affection. You should know if the Second Date will happen in this Episode. If Sonico went to the bar with Taro, the Second Date would occur.

Episode 5
Another important Episode. After the shoot of this Episode, Sonico will enter one of the five route, separated by 5 columns.
To make it easier, I will name the route A, B, C, D and E, from left to right





























Episode 6
The route that has been locked after Episode 5 shoot will start. Keep in mind that since the route is locked, even if Sonico moves to another column after this shoot, the subsequent story will still be played out accordingly to the one in the locked route.

Episode 7
After this Episode, you will witness one of the 15 Ending, based on the locked route and your current location of the grid (unless you are going for True Ending, or your client's satisfaction is below 70% on average).
Basically, the Ending that you get is from the square of the locked route that is on the same row as your current location.
To put it simple:
+ If you entered route C and ended Episode 7 in square 9, you will get Ending 9.
+ If you entered route C and ended Episode 7 in square 6, you will still get Ending 9
Also, the lower middle row (which has no number) shares the same number as the upper middle row.

Since I have explained how the branching system works, I just gonna list all 15 Achievements related to the 15 Normal Endings, for the sake of completeness.
It should be worth noticing that the Endings in the corner (1,3,13,15) have lower acquisition rate compared to others Normal Ends. The reason is that it takes a longer distance to travel from the center to a corner. So, after you have unlocked the Ouka shop, you should have a look at some outfit Sets in the shop. While matching various outfits may end up moving Sonico even further to any desired direction, using Set is more simple, universal and useful when you have not ♥♥♥♥♥♥ many outfits, so I will list some Sets that can advance Sonico considerably to corners.

• Upper left: Galaxy One
  
• Lower left: Fluffy Snake Muffler
  
• Upper right: Meruru
  
• Lower right: Bunny Maid

I will put back my route naming scheme her for reference:





























Route A Ending

Super Gravure Idol
Get Ending 01.



Enter Route A and Finish Episode 7 on the top row.



Fashion Leader
Get Ending 02.



Enter Route A and Finish Episode 7 on either of the middle rows.

Get Ending 03.



Enter Route A and Finish Episode 7 on the bottom row.


Route B Ending

Commercial Queen

Enter Route B and Finish Episode 7 on the bottom row.


Quick note: In case keep getting Bad End in Episode 7 of this route, it is because you have selected a choice at this scene.
Just do not chose anything, wait a bit, all the choices will disappear and you are good to go.

Route C Ending

Across the Sea
Get Ending 07.



Enter Route C and Finish Episode 7 on the top row.



Flower of the Battlefield

Enter Route C and Finish Episode 7 on the bottom row.


Route D Ending

Enter Route E and Finish Episode 7 on the bottom row.

During the game, from time to time, you will have the option to select dialogues or interact with Sonico. You can use these opportunity to increase her affection. In general, the affection does not have anything to do with getting any of the 15 Normal Ends. However, it is necessary to get the 2nd date, and unlock the True End.
The dialogue/interaction guide to reach high affection is available here: Pastebin[pastebin.com]
Some other choices may give affection as well. I did not even follow this guide. You do not need to follow this guide exactly and still can get the Second Date, True End, etc.., so altering a few choice will not hurt. Also, voice bubble choice has nothing to do with affection.

Unlocking the Second Date

Intro:
+ Look: Face
+ Touch: Face

Episode 0 / Prologue
+ "Sonico, then"
+ "Sorry 'bout earlier, my bae!"
+ Look: Body
+ "Relax, Relax"
+ Look: Face

Episode 1
+ Touch: Hand
+ "It's a guitar case, right?"
+ "I'm sure you will be able to keep playing" (You need to wait a bit for this choice to appear)
+ "You've got to be more careful"
+ "It's fine. Relax"

Episode 2
+ "Umm"
+ Look: Face
+ "Look. You're all tense!"
+ Touch: Hand

Episode 3
+ Wait, and don't do anything
+ "How had the work been so far?"

Episode 4
+ "It suits you perfectly"
+ "Should we hold hand?"
+ "Which one do you want?"
+ "Maybe not"
+ "Sure, but I don't eat them often."

Episode 5
+ Look: Sonico
+ "I know what I said earlier, but..." or "It's fine. I'm sure we will win!"
+ "Come to think of it"


Exciting Date
Go on a second date with Sonico.



Get enough Affection with Sonico before Episode 4 ends to unlock this Achievement.

Unlocking the 2nd Date is really important to get some Achievements, not just the True End.
Use the above choices for other purposes if you need them. For now, let's move to the True End.

Unlocking True End
In order to unlock the True End, you will need to prepare a few things:

• Complete at least 1 Ending from each route (column).
  
• Get Sonico affection really high (naturally, you should have unlocked the 2nd date in the process)
  
• Make sure you are at route A after episode 5 shoot. The True End is branched from the story in route A.

Continue from where we left off:
Episode 5-2 (the Second Date)
+ "I'm listening" (You need to wait a bit for this choice to appear)
+ Look: Nothing (Wait)
+ Touch: Hand

Episode 6:
+ "This coffee this pretty good"
+ Touch: Hair
+ "To move people with your music"
+ Voice bubble choice: Doing everything correctly and you will have the option to call Angie or Sonico. However, calling Sonico will proceed the route A story normally, so you will want to call Angie for the True End.
+ Any option

Interlude:
+ "It's been like this ever since that day."
+ "No, that was the first time."
+ "Let's do our best on our next shoot"

Pass the last shoot and you will enter the Finale, where you can get the two Achievements below.


Just between Us
Reach maximum affection with Sonico.



When you reach this screen, take action. You will know what to do.



















Super Orbital Rock Star
Get the True Ending.



Following the above section to proceed the story and you will get this Ending eventually.

Other Endings
Besides the 15 Normal Ends and the True End, there are two Extra Ending.

Punkish!
Get Extra Ending 01.



After the final shoot of any Normal End (not sure if it works with the True End, but not a big deal anyway), if you average client's satisfaction between all shoot is below 70%, you will get this Ending, although I suggest getting it below 60% for Extra clothes.



Ultimate Weapon
Get Extra Ending 02.



It has been said that before unlocking this Ending, you need to unlock the 15 Normal Ends, True End and Extra Ending 01. While I do not think it is necessary, I cannot confirm because I have already unlocked every other Good Ending before getting on this one, so let's just stick with it for now.
Okay, once you got the above requirement, start a new game. You need to touch and talk about Sonico's headphone whenever you have the opportunity to do so. There will be four scenes available: one in the Intro, two in Episode 00 (Epilogue) and one in Episode 2.
After doing that, in Chapter 5, select "You've got your own secret weapon!" at this scenes.
Enjoy!

Sonicomi Master
Get all good endings.



If you have followed everything correcting, unlocking the 15 Normal Ends, the True End, and the two Extra one, this Achievement should pop-up, possibly right after you got the Achievement Ultimate Weapon.

At the time of writing, Doomed Wanderer is currently one of the four most difficult Achievements to get, tying with the three outfit-unlocking Achievements, which is insane. The data for unlocking all Bad Ends is lacking, and the process is tremendous.
According to JAST USA/J-list, this game has 22 Bad Endings. I can only be sure about 20 of them, and I believe there are only 20 of them. But I will put some of my experience about what could be the other two. Do not worry about the others too much because you might have done it at some point without noticing. Of course, if somebody can help me clear things up here, it would be great. At the end of the day, all you need to do is following my guide below and everything will work just fine.
You will also unlock some other Achievements in the process.

Bad End 1-18: Failing the shoots
If you have read my Ending Achievements part 1, then you should know how the branching work.
Now before doing this, I highly recommend you to create saves file or each of the five routes. You will need to load a lot of saves. Also, take note of what Bad End you have ♥♥♥♥♥♥. I forgot one of them during the process. I did not know which is which, so I have to replay all. Not a very fun experience.
Episode 0, 1, 2 and 3: They all have only one possible scene, so each of these Episode will give you 1 Bad End.
Episode 4: It is always the first date so no shoot, obviously.
Episode 5: The game separates into there branches here, related to three Second Date scenes. Each branch will give you 1 Bad End, so Episode 5 will give you 3 Bad End in total.
Episode 6 and 7: There are five different routes, so each of these two Episode can give you 5 different Bad Ends, based on your route. We are talking about 10 Bad Ends in total, for these two Episodes.
True End: Fail the last shoot of True End route gives you 1 more Bad End.
Totally: 4+0+3+10+1=18 Bad Ends.
See my point? Tremendous.
So, yeah, if you want to do this, make sure you have create a lot of saves that involve every route. Plus, once you got a Bad End, note it down. It is very easy to mess up one problem when you have 18 of them to solve.
When you get to the shoot, just do nothing for about a minute. You will get all Bad results, draining Sonico energy, and she will fall down shortly, thus ending the shoot.


Snap out of It!
Take no photos during the tutorial.



The tutorial part is a bit confusing. You will get this Achievement if you do nothing on Episode 0 shoot, not the tutorial.



Lost Photographer
Get a bad ending.



Do nothing in a shoot is the easiest way to get this Achievement.

Once you got all 18 Bad Ends sorted out, you are over half way.

Bad End 19: Route B, Episode 7 Bad End
Remember this scene?
Simply pick an option and advance the story for the Bad End to occur.

Bad End 20: Second Date Bad End
This Bad End is only unlockable in the Second Date of the Niche area (Ending 10-15). So make sure you advance to that direction.
In order to get this ending, basically, you need to be a pervert by touching and talking about her boobs a lot, but you will also need to gain enough affection to get to the Second Date. I think there are more than one way to do this, still I will put my way of doing it below. At these scenes, touch or talk about her boob, otherwise, just do as you normally would to gain lots of affection.
Then in Episode 5-2, the Second Date, of the Niche area, when she talked about the clothes being too tight, wait for the option "Have you gained weight" to appear, select it, and keep touching below her waist several times.
A cut-scene will appear and you will get the Bad End. On my play-through, I got the Achievement right after obtaining this. I think there are only 20 Bad Ends, but since JAST said 22, I will put some more information below, hopefully someone can help me confirm this on a better day.

Bad End 21-22: !?
These Bad End should be somewhere in this mixed bag. Again, this info was given by JAST. I have no idea, and I do not think they are necessary, but thanks to JAST, I got the Bad End 20, so I think these info is worth checking.
- The "Punkish!", aka Extra Ending 01, is counted as a Bad End, according to JAST. I am not very sure about this, because it earns a place in the Menu -> Ending List, but since the Ending is quite negative, I can see it is a possibility.
- If you go for the special Ending 2 before unlocking all 15 Normal Endings then you will get the Bad Ending in which Taro get killed by Kitamura. However, in my playthrough, I have never got that Ending (I only did the Special Ending 2 after finishing 15 Normal Endings, so I permanently missed that) but still got the Achievement so I am not sure about this one.
Anyway, I believe that's about it. That is all I did, and I got the Achievement.

Doomed Wanderer
Get all bad endings.



Do everything I mentioned here and I am sure you will get the Achievement. If you have any problem, make sure you do not mess up at the first 18 Bad Ends.

There are a few other Achievements left, so I will list them all here, except for the three outfits collecting Achievements. They have their own class.


Scenery Photographer
Unlock all backgrounds.



Honestly, I do not understand the true mechanic of this Achievement. I was able to unlock this Achievement around the same time I complete the True End route, but I still got like 7/15 Endings of the grid that I have not finished, so I do not think it is about the shooting location, but also not related to see all of the game backgrounds either. I think it is more like see all type of background. Anyway, I believe if you are going for all the Good End, you will get this Achievement anyway.



Hair Master
Unlock all hairstyles.



On Second Date, Sonico will ask you if she should change her hair style. See will ask you 2-3 choices, and there are 3 possibles dates scenes, so like 8 choices in total. If you want to get this Achievement as soon as possible, simply reload and select every choice (but you must skip probably til Episode 6 shoot for the hairstyle to be added to your outfits).



Millionaire
Buy everything in the Ouka Shop.



Translated to: grind a load of Sonicoin. If you want to go for all the Achievements, this part is probably redundant because the Achievements Accessory Master will require you go play like...a lot. However, if you just want to get this Achievement then here is my Sonicoin Grinding Strategy:
+ Grind coin in the Photo shoots section (Menu Extra -> Photo Shoots)
+ Use either client Hanzo, St-Sna or Club XEGA (because they require only 1 take, and the location is not locked).
+ Select the shooting location: Even Hall. The Enthusiasm gauge charges quite fast here. You only need to change position once on each level before the gauge is full. The number of circles is also quite high too.
+ Only use Hard Mode, and do not break the combo.
In case you are wondering why we only use with 1 take, it is because we have full 3 minutes for that shoot (2 or 3 takes only do 2:30 each). When you get the combo really high, the score for each shoot is massive. Therefore, the last 30 seconds (16.7% of your time) may account for like 30% of your score, if you do not break the combo of course. Do everything correctly and you will get well over 1K Sonicoin per shoot. This is how it looks like if you do everything correctly.



Workaholic
Complete all Client Requests.



- The first client is: You. Unlock this client by trying to shoot something at the Menu Free Mode.
- The next 2 clients are unmissable, for Episode 0 and1 shoot.
- The next 2 clients are for Episode 2 shoot, depends on whether Sonico is on the Mainstream side, or the Niche side.
- The next 4 clients are for Episode 3 shoot, depends on Sonico position on the four quarters of the grid.
- The next 6 clients are for Episode 5 shoot. Remember Episode 5 has 3 different scene areas? That, combined with whether Sonico is on the Energetic side or the Mellow side will give you 6 clients.
- The next 10 clients are for Episode 6 shoot. 5 columns/routes with either Mellow or Energetic side will result in 10 different request.
- The next 15 clients are for Episode 7 shoot. Each numbered square has a different client, just like the 15 Endings, so depend on which square you are on, you will get the corresponding request.
- The last 2 clients are related to the True End.
So there you have it: 1+2+2+4+6+10+15+2= 42 Client Request. Good luck.

And here we are, the grand finale: the Achievements for getting all the outfits.


Clothing Master
Unlock all clothing items.



Get all the clothes.



Accessory Master
Unlock all accessories.



Get all the accessories.

Getting these Achievement is obviously an arduous task. Honestly, I am not exactly sure where to get any specific piece of outfits, BUT i can give you a check list of what you should do, and you should follow it from 1 to 5 in order, because things will get really messy further down the line:
1) Get all other Achievements, especially the 18 Endings one and the all Client request one.
Basically, every time you see a new scene with a new outfit that Sonico wears, you will get that outfit at the end of that scenes, so by getting the above Achievements, it's a guarantee than you have watched all the main scenes.
2) Play again and again to select all available option during a dialogue, especially during the Date Episodes (4 and 5-2).
Some special scenes will award you a certain outfits, so it's better to see them all. Also, the Date episodes may contain quite a few surprise.
In the First Date, at this scene, wait for a bit for the option "It could work" to appear and select it.
Proceed to Episode 6, on either route D or E (Niche side) to get the Light Tan.
In the Second Date of route C, at night (you will need a certain about of affection for these choice to pop-up), select "Maybe we should stand closer", then touch her boobs, then a special scene will occur. Finish the Episode for a new outfits.
These are the scenes on the top of my head, that I think important and tricky. All in all, the moral of the story: check every option.
3) Get the Puskin Ending with less than 60% satisfaction for Bondage (cast off).
Basically, just skip every shoot except the final one, and finish it with 0% satisfaction and I think it's a guarantee to get this Achievement.
4) Finish every client shoot on Hard mode with SS rank.
When you play on the hardest difficulty and get a SS rank, you are guaranteed to get all possible outfits from that client. There are 41 Client you need to get, so, yeah, good luck.
At this point, you should have ♥♥♥♥♥♥ Clothing Master. If you have not, do not continue if you have not ♥♥♥♥♥♥ Clothing Master. It will just make everything become a mess. Instead, check 2 again.
5) Get all the random accessories from all shooting location.
Accessory Master is harder to get than Clothing outfits, because getting all accessories requires certain element of luck and randomization...LOL. Why Nitro plus thought this is a great idea? I don't know. Anyway, if you shoot at certain location (time of the day does not matter), there is a chance that you will be awarded with a certain accessory. So in order to maximize you chance and minimal the time:
+ Choose a client that requires 3 takes.
+ Equip outfits, and shoot to get SS rank, WITH Bonus Stage.
+ Choose the client that has the default location that you want to grind. (Ex: if you want to grind at the Café, choose the client with 3 takes, and default location is the Café)
By doing so, I think you are guaranteed to get the missing accessory (if any) in every 3 shoot max. So, just for worse case scenario, keep taking shoot at a location and if you have run 4 straight shoots without getting any accessory, chances are either your luck is REALLY REALLY REALLY bad, or you have ♥♥♥♥♥♥ all the available accessory from that location.
At this point, you should get Accessory Master.
Interesting theory: I cannot confirm nor deny this but it makes sense, so I will just put it here. It was come up by Monty Sigurdson. Probably the random drop is determined by shooting the sub-targets. If you photographed a sub-target (animal) and successfully got a random drop, there will be some kind of different sound. Need more confirmation but I will just leave it here. It is really nice discovery if turned out to be true.

If you have done from 1-5, you should have ♥♥♥♥♥♥ both Clothing Master and Accessory Master. So you may think: True Somicomi Master should pop-up too...
NOPE! LOL. This Achievement is confirmed by Nitro plus to get bugged. You may not get it, even though you have actually ♥♥♥♥♥♥ everything. At the time of writing, Nitro plus is assisting JAST to fix it, so, yeah, we cannot do anything but wait.
YES! They fixed this Achievement. If you got the two previous clothing Achievements, this one will unlock automatically for you


True Sonicomi Master
Unlock all outfit parts.



Take a moment to look at this Achievement. If you have ♥♥♥♥♥♥ it, it means you have achieved something that only few man have ever done. You are legend.
Thank to Sinful Sorcerer: Not only you need to unlock all outfits, you also need to get all hairstyle and all tans.

1) Note that a very few users have reported that this specific Achievement is bugged. It is actually the most common Achievement but, for some reason, if you fall into that tiny minor few then move the Save and Data folder (see Tips 6) to somewhere else (cut/paste). Start a New Game, do this Achievement, then restore the previously moved folder to its original location (delete the new folder that appeared there). Also, even if this Achievement is bugged, it should not affect the next one, so you just need to do this once.
The Easiest-to-get and the Hardest-to-get Achievements are both have issue. I wonder why T.T
2) A HUGE THANK to Nicholas from JAST (Nope, he just won't accept my friend request T.T), and Mike for helping me with this guide.
3) If you want to share anything, don't mind comment below.
4) Apparently the one who is in charge of making Steam Trading Card for this game at JAST somehow forgot about one of the most important character Cutie Q (aka Lumie). Just... HOW?
So, yeah, I give you the ONE AND ONLY Cutie Q Trading Card
