When Life Gives You Grapes, Spike the Soda

Why Mystery SaiOuma Fanfiction Works So Well
Oma Kokichi/Saihara Shuichi — V3's gentle detective and its self-proclaimed evil supreme leader play a season-long game of lies, with Kokichi needling Shuichi precisely because he is the only one clever enough to be worth deceiving. Kokichi's death gambit makes the detective the executor of his final, unreadable plan. The fandom obsesses over which of his lies about Shuichi were true.
Mystery — Something is wrong and someone must work out what: disappearances, ciphers, impossible crimes, and secrets with bodies attached. Mystery fic includes whodunits, slow-unraveling secrets, and stories where the reader solves alongside the characters.
A liar who wanted to be solved and the one detective who almost managed it before the curtain fell. A fair-play mystery makes the reader a participant, and fandom's deep character knowledge makes the misdirection more fun — you know these people, and you're still wrong. That's why mystery SaiOuma fanfiction is one of the most consistently popular combinations on AO3.
