I want to make a pure and honest guess about who the culprit is for this trial. Click Read More if you want to see my guess and why I thought that I think it's Mitsuhiro Higa The way the rope was thrown implies that it had to have been thrown from outside the bathroom, saying that the culprit is a boy. This is the reason why Kiyota was being hanged, to draw suspicion to the girls. This eliminates all the girls from being the culprit. The original victim was supposed to be Tsurugi but with the nameplates switched (accident by Haruhiko), they slid the note under Kiyota's door, thinking it was Tsurugi and when they (murderer and victim) arrived in the laundry room, He noticed he made a mistake but was too far gone and had to kill Kiyoka instead, afterwards needing to change their plan. This eliminates both Tsurugi and Haruhiko from being the culprit (Tsurugi being the original victim and Haruhiko mixing up the nameplates). After that, I'm using my own opinions. The most muscular usually die in the 4th trial, so not Kakeru. Kinji acts to quietly and seems suspicious, so not him, I've accidentally seen Super Danganronpa Another 2 before watching this, so not Teruya and that only leaves one person, Mitsuhiro.
I think the culprit tried to kill le police man, and Haru is kinda sus, but idk if his the culprit or not, i will avoid comments so i wont get spoiled, i got spoiled by every danganronpa/fanganronpa, but not this one :)

I think it’s Akane. Don’t hate me for saying that. But here’s why I think so. She’s the only one who went to the antiques store besides Teruya. She would know what’s in there because she likes valuable things. She’s also the Ultimate Maid who knows how to clean up messes, and since she’s a girl (or identifies as a girl) she is able to go into the girls bathroom to hang Kiyoka.
Even though I’m 4 years late, I still think Setsuka is the killer. My next guess would be the cheerleader (can’t remember her name), but Setsuka just seems more suspicious
I feel like that the nameplates aren’t even that important as they were in chapter one of trigger happy havoc, and that haru might’ve honestly just mixed them up, a bit too obvious tbh
