Dreadful Musician: Subverted. He's very talented, but he has an atrocious singing voice and it's easy to get sick of his music considering he always plays it at the highest frequency avaliable.
Dumbass DJ: He's the SHSL DJ, and definitely not the smartest person in the cast.
Genius Ditz: While he's a decently nice person, Miyata is cowardly and slow to process situations. But he's amazing with music.
Bodyguard Babes: She's the ultimate bodyguard, who happens to be a girl.
Jerkass Has a Point: While Kitamura is not a jerkass, her tendencies to isolate herself and distrust everyone can make her come off as one. However, these tendencies are perfectly reasonable, considering that the cast is literally on the island to murder people.
Red Is Violent: She has flaming red hair, and won't hesitate to pull out a weapon on someone she finds threatening.
Julianna Montgomery - SHSL Pageant Queen
Expy: She's the token European of the group, with long blonde hair, elegant clothes, and nearly perfect manners. In addition, her title has connotations of royalty involved. Does this remind you of a certain princess from SDR2?
