The young master's sister falls in love with a unexpected person, can they make it work?

I decided to do a rewrite of Trigger Happy Havoc with the same storyline but with different victims, blackends(killers), survivors, and a mastermind. The original idea is from Tik Tok but in my rewrite the protagonist is Toko, the support is Isahmaru, and the antagonist is Togami (some things never change do they)

like the title says^^ except only 16 characters can enter... who will be lucky enough to enter~? ...Oh gosh, I sound like Monokuma... (Closed entry until next entry)
