If you want to stop being a scrub and carry your team like a f***** boss every match, you need to unlock the most OP merc in Dirty Bomb - Kira The Kawaii Killer. But to really master Kira and her Sattleite of Death you need to learn to think like Kira, dress like Kira, smell like Kira — you need to become Kira. And the most important aspect of being Kira is, of course, you need to talk like Kira. Which is why you have come to this guide.

At this stage (since I'm too lazy to add any other content) this will just be a list of useful links for people who want to be a better weeaboo, or, hopefully, those who actually want to properly learn Japanese.

Kira doesn't have a lot of phrases in Japanese, but here are the ones I noticed (please tell me if I missed any!):

Kira キラー - "kirā" means "killer" in Japanese (a borrowing from English)

Kawaii! かわいい (or 可愛い) - kawaii (cute in general). Spam it with V-5-7.

Banzai! ばんざい (or 万歳) - traditional Japanese cheer, roughly "Long Live!" E.g. "Tennōheika Banzai!" (天皇陛下万歳), "Long Live the Emperor".

Hontō ne? ほんとうね (or 本当ね) - "Really?"

Hai! はい - "Yes!"

Arigatō gozaimasu!: ありがとうございます - "Thank you" (polite).

Dōmo arigatō gozaimasuどうもありがとうございます - "Thank you very much!" (polite)

Dōmo arigatōどうもありがとう - "Thanks a lot!" (slightly less polite)

Arigatō, doctor!: ありがとうドクター - "Thanx, doctor!"

Dōmo, doc! どうも - "Thank you, doc"!

Tantō no! 短刀の - tantō is a short sword or a dagger, but not sure what the whole phrase means. @Ice³ proposed the following explanation: "The phrase "Tanto no!" does not refer to the dagger here. It means "A lot" or an "Excessive amout... According to the DB wikia the quote is triggered when she gets a melee kill. My theory is basically based on the fact that it makes more sense and it sounds the same. I think it's a pun. This kind of phonetic puns are quite common in the Japanese language.". So basically she says "a thousand No!" or something like that." Would be nice if anyone could confirm or disconfirm.

Sayōnara, idiot! さようなら - "Farewell, idiot".

Dōzo! - どうぞ "Please!" (when offering something).

Deau mata! 出会うまた - "See you later!" / "See you round!"

Chotto, stop shooting! ちょっと - "Just a minute!" / "Hey!".

Konnichiwa! こんにちは (or 今日は) - "Good day!" (polite daytime greeting).

Yamete, stop shooting at me!" やめて (or 止めて) - "Stop!"

Iie, no! いいえ - "No!"

Tadaima! ただいま - "Here I am!" / "I'm back!" (usually said when you come back to you own home; Kira says this when she respawns, presumably?)

I feel genki! 元気 - "Genki" means health, vigour, energy etc.

Genki desu! 元気です - literally "I'm healthy" / "I'm full of energy", usually translated as "I'm fine".

Gomennasai! ごめんなさい - "Excuse me!" (polite)

Gomen! - ごめん - "Sorry!" (less polite)

Too bad, so sad, you're dead to me, you're sashimi! - Sashimi (さしみ or 刺身) is traditional Japanese dish made from meat or fish sliced into very thin pieces.

Textbooks:

• Genki: An Integrated Course in Elementary Japanese – a solid textbook for absolute beginners;
  
• Minna no Nihongo – good textbook for a somewhat more advanced level;
  
• Remembering the Kanji (by James Heisig) – approach with care: I highly approve of Heisig’s method in general, but I strongly object to certain choices he makes as to keywords, radical names and the order in which kanji are given in the book. If you're going to use Heisig, check out the community website: http://kanji.koohii.com (it's awesome!).

Disclaimer: I myself know Japanese at the N3 level, meaning I'm not a native speaker or a certified teacher, so please take everything I say with a grain of salt. (Yes-yes, I'm actually just a weeaboo - *it's ironic paradox*.)

• 1) Learn some basic phrases: https://en.wikivoyage.org/wiki/Japanese_phrasebook
  
  
• 2) Listen to how they are pronounced http://www.forvo.com/languages/ja/
  
  
• 3) Start learning the Kana (Japanese alphabet, which has 96 letters total!). I would Suggest trying Heisig's mnemonic method first: https://nirc.nanzan-u.ac.jp/ja/files/2012/12/RK-Hiragana_sample.pdf and the video: https://www.youtube.com/watch?v=EKh9MQOaZ7I
  If it doesn't work for you, then stick to the rote. In any case, check out the MLC worksheet: http://mlcjapanese.co.jp/Download/HiraganaKatakanaWorksheet.pdf
  Note: it took me two weeks to memorise all 96 Hiragana and Katakana. Some people can do it in less time probably. Continue learning phrases and basic words while you are at it!
  
  
• 4) If you are still interested in Japanese at this point, get a textbook. I would recommend Genki (you can find it online, note, it comes with excellent mp3 listening materials).
  
  
• 5) It's a great Idea to learn through the various media like anime/manga/games etc. When you are in doubt which words to learn and which to omit at this point, I highly recommend you use this list: http://www.tanos.co.uk/jlpt/jlpt5/vocab/ These are the basic phrases and expressions you need to pass the N5 (lowest) level of the Nouryoku Shiken exam.
  
  
• 6) Start learning Kanji as early as possible. I recommend Heisig's method (Remebering the Kanji), which is to break down Kanji into parts and learn through stories. But I highly oppose his proposed order (行 - iku, for example, is #873, why?!). So basically I suggest you look at the book, understand the method but then take the N5 Kanji list (http://www.tanos.co.uk/jlpt/jlpt5/kanji/) and just stick to it. Then, if you survive thet, proceed to N4, N3 etc.
  
  
• 7) Consider taking Nouryoky Shiken exam in your country (http://www.jlpt.jp/e/application/overseas_list.html). I think it's an excellent way both to encourage yourself to study, to consolidate what you have learned and actually get a tangible real-life result (imagine how good it would look on your CV). The official estimate for preparation time for N5 level is 300 hours, compare it with the playtime you have in some of the games on Steam!!

Or you could just find a proper teacher and not listen to weebs like me on the internet :3

Hope this guide was helpful and/or fun! If you find any mistakes, or have any suggestions (or maybe a missed one of Kira's phrases), please leave a comment below! Learn Japanese and plaaaaaay dirty!!
