So firstly head to the games installation area, such as Common on Steam or wherever you have it placed and open it up and you'll be greeted by 4 Icons, Binary, Readme, Steam_api64 etc

Now that your here, head to Binary and locate the Character folder




Now that your here, here comes the somewhat tricky part replacing Yuri with Miu.
Now that we're in the Characters folder, scroll down til you reach the file name of H_MIU_A As this model is the playable model from the chapters she is in. So now drag that folder onto your desktop and rename all the files to H_YRI_A then drag all said files into the H_YRI_A Folder and Boom you're done with modding Miu as Yuri





Editor Notes* Some cutscenes will look rather funny from Miu's face model taking over Yuri's only do this mod if you've already beaten the game.

Editor Note 2* From testing said files the only ones you need to rename now are the files that that start with GAPK and GMPK respectively

So if you wanted to use other outfits or play as other people other than Miu (Not sure why she's epic)
Now you can as I've done the painstakingly annoying grunt work for you, the list below will show each file types outfit all laid out.

Editor Note - None of this works on Ren doing so will crash the game, Sorry about that.
I would of put a link for a preset easy version but Steam won't let me so if you want it, just DM me for it.
Editor Note 2- Make sure to install Miu Default first for the face bones then the outfit you want.
