Why would he be?
Because his sister seduced him repeatedly until she came on him?
Because his other sister raped him after trying to cut his dick?
Because he was ensnared by an exhib girl and taken to an orgy where she basically NTRed him?
Because he had sex with the girl his sister pushed on him?
Because he made that girl and sister understand their feeling for each other?
Right i feel like sora was a victim and it all started with the big sister but then again i think the big sister became attached to him and that formed into a twisted love because she lost her mom
Sora is an asshole
