Noticed a lack of the romance tag. Does MC never get the girl or does she just get raped a bunch?
I've seen/heard of mangas that don't start with romance tags despite things going in that direction, only to later get said tag, so if we ever continue to get updates we could see it added later.
This seems to be leaning more heavily towards a harem outcome, even if via unintentional brain washing, but I could only really see a believable romance between mc and Hiori, and maybe the childhood friend if the mc can overcome his internal crisis before that ship sails.
