It's coping mechanism. Everytime he was raped he imagined he encountered aliens.
Wait, so every time he saw aliens he was raped???? (￣∇￣") ┑(￣Д ￣)┍
Rape is not sex!
Sorry........ I don't like that word very much, it pains me how people do these kinds of things. ╥﹏╥
He was gangraped. That's why it showed him being "abducted" by "aliens". If you check, there's side pictures showing what he was imaging, and what was actually happening. http://www.mangago.zone/read-manga/ore_higaisha/nbt/manga/ore_higaisha/c004/pg-13/
Oh.... I see now. That's really sad.... a young boy.... ╥﹏╥
