Danganronpa 2 HOT chapter 1 predictions

Chapter 1:

Byakuya killed, pretty obvious. Next time you are going to drop in the knowledge bomb (in the kitchen), just do it because if you don't it's your death sentence. Still, I guess that will come into play in Chapter 6; it is probably something about his appearance in the previous game, the bait letter and blah blah.
Killed from the secret passage/underground, murdered hid the knife on the table with that tape that can be seen during the night, or that was the bait that Byakuya took, all the AC + the iron machines made the power outage. Still don't 100% see why swap the cloth, and potentially could have been killed after the outage (while everyone goes away to look for shit), but I haven't meditated about who went outside and who didn't.

Predictions: (I more or less know how he was killed but not the killer 100%)
Honestly, no idea who killed him.
- Akane: Could be, probably not. Annoying character that was eating so probably nope, it will stick around to annoy more (though not endgame character, guess chapter2-3)
- Chiaki: She was outside, and this girl is probably endgame, so nope.
- Fuyuhiko: Obvious/Bait, he didn't, would be surprised if he did.
- Gundham: This guy is endgame, and he definitely is not the killer, specially after he reveals the hidden passage from fire door/bathroom.
- Hinata: Mom I promise I didn't do it :) (This is not that character so we are stuck with it)
- Hiyoko: I really wish she was, just to remove her from the game. Honestly could be, but annoying characters die in chapter 2-3.
- Ibuki: This character has more potential than a chapter 1 killer.
- Kazuichi: Same as Ibuki, wouldn't be that surprised if he was, but still unlikely imo.
- Mahiru: Same as in the Ibuki/Kazuichi pack, but not as endgame as those, probably chapter 2/3.
- Mikan: Doesn't strike me as the killer, devs have to put more fanservice shots.
- Nagito: Endgame character, nuff said.
- Nekomaru: This guy could have done it, though not really an alibi, still idc if he did or not. Probably not because he wanted to go to the bathroom
- Sonia: Don't kill her yet BibleThump. Still I don't think so based on fanservice for waifus.
- Teruteru: at this point idc lmao too much written, ima go play
- Peko: she could have done it honestly, she was missing but I think it's too obvious.

Suspect list IF I HAD TO GUESS: Hiyoko, Nekomaru, Peko + Teruteru?
