I think the theory that he is an alien returning home fits more.... Reasons: 1) Alien and space topic continues to pop up.. at the Gokun he was asked if he believed aliens existEd and he said that they could be aliens themself.... he keeps mentioning he wants to have a career in NASA or going to America to take part in some research or becoming an astronaut... 2) the weird bizarre things he do and sometimes it seems he doesn’t seem like human or common sense/knowledge of how society is 3) another is during the last chaps when he was talking to the Sempai in the nurse office he said he rather go out and discover new land or whatever it could be taken as he come to study human and maybe want to take over 4) transfer student is the perfect cover plus it’s sakamoto if he just only moved to America for him it would totally be easy to meet them again but if he is going back to his planet it would be harder so that why he showed his emotions .....My theory is he is not dying but he is an alien
