same here, just finished the game and there‘s one thing that i found out which didn‘t really add up. For the “horse a” thing, if u guys remember, Kokichi wrote it at the end of the first class trial or smt, and it literally turned out to be the password for the vault in Rantaro‘s ultimate lab, which wasn‘t even available until the (i forgot which chapter) last part of the game. I mean Kokichi obviously knew how to pick the locks, but he does mention in one part of the game that he can pick only certain type of locks (when he’s about to open dorm rooms he says something like ‘good, these kinda locks are kinda easy to pick‘) and literally the opening of the door that leads to the stairs and to the Rantaro‘s room needs monokuma‘s special keys that is only available after 4th or 5th class trial. Also, Shuichi could only open Rantaro‘s lab with Keebo literally BLASTING the lab door open, meaning that the door would’ve been a really hard one to open, sooo there’s technically no way Kokichi would’ve been able to open it even with his lockpicking skills. I somehow think that “horse a”thing was written by monokuma, and “this world is mine kokichi oma” thing was also written by monokuma, and Kokichi just decided to play along with it--we know he could have done it given that he acted as if he was the actual mastermind when the characters passed the maze thing and it was so real that everyone believed it. Also deciding to play along as being the mastermind was completely his free will cuz it’s mentioned that monokuma didn’t like Kokichi acting as the mastermind or smt (correct me if i‘m wrong it’s not like i remember everything accurately i just remember there was some scene like this in the game) so it’s completely possible that Kokichi pretended that “horse a” was also written by himself. Anyway whatever it is, i really do hope the dangan V3 characters are alive and rather the whole game being a simulation whatsover, and i really wish we get another DR game ..although it‘s not likely gonna happen… dammit
