Ok, i'll use the proces of elimination to find out who the killer is.
The body discovery announcement only goes of when three innocent students find the body, which this time are Pedro, Akumaira and Azxytiu, meaning they are innocent.
There was a blood puddle on the edge of one of the dryers, so i think the killer pushed Javon to the dryer in anger, which would explain the back of Javon's head bleeding. So, it would make sense that whoever the killer is was either really angry at Javon, or could just be easily angered in general. This leaves only 3 suspects:
Takarou (who was angry at Javon for trying to tell everyone his secret)
Tal (who could be annoyed by Javon fangirling over him)
And Syno (who gets angry when annoyed).
I'm not really sure which of these three it is, but i'll take my time.
1st: Shadow (also the only one to finish the spinner part alive, everyone else died there)
2nd: Magenta
3rd: Lime
4th: White (was actually 2nd, but Maroon went past Magenta and Lime and she was killed first)
For some reason, i'm actually pretty happy that Magenta won. She was friends with two of my favorites, Cyan and Yellow, and she was actually quite nice.
