This... my brain just came up with a solid theory... this all started? when he got injected with the fluids... who injected him? the doctor... what does the fluids do? make you delusional about someone being after you... this is what MC also went through in chapter 1... when did it start? could be when he visited the hospital after Rena pushed him into a corner... Ooishi-san is the one who started putting ideas into his head... but the injection is the reason he went full crazy... why Rena and Mion were also acting crazy? could be also injected... what are the supernatural stuff then? Rika causing the end of chapter 4... then how did MC have 2 copies in chapter 2?... same reason with the bodies being dead and still moving around... something that is either done by another power like Rika's... or the doctor learning a way to control them... what did the blonde girl do? she is either controlled... or she did fake her death and cause lots of sheeit to happen... i think this theory is what i will go with for most of what i got without rereading anything ,_, *don't tell me anything or i will stop reading your posts again V-V*
