Back when I still made DRAT, these were the rules I used for writing each character in the show:
Naegi: Every line must he says must either be terrified, snark or terrified snark.
Kirigiri: 100% done with everybody’s shit 100% of the time. Basically somebody who has played Danganronpa already and is on a New Game+.
Ishimaru: ALL DIALOGUE TO BE WRITTEN IN ALL CAPS. NO CONTRACTIONS USED. CATCHPHRASE CITY BITCH.
Maizono: Weeaboo Sydsnap. Also regular Sydsnap.
Asahina: Embrace the donuts cliché and ride that thing to the goddamn moon. Anything else is comprised of Lady Nanaki’s improv.
Celes: Calm, refined lady on the outside, actual fucking demon on the inside.
Genocider: Pretty much canon, only cockney.
Hagakure: Homeless Yamcha.
Sakura: Generic Street Fighter character.
Chihiro: BE EXTRA CAREFUL WITH EVERYTHING THIS CHARACTER SAYS OH GOD DON’T MAKE THE SLIGHTEST MISTAKE JESUS CHRIST
Alter Ego: Maizono Mark 2. Only less Sydsnap and more MasakoX being a dating sim heroine.
Yamada: Any real life, socially awkward gamer I’ve met. Also me.
Oowada: Every angry tough guy character ever.
Leon: Talks in “dude” voice. About as subtle as 1,000 baseballs to the face.
Junko: Extreme valley girl, like somebody trying to deliberately put on the act. Hmm.
