ok, I have to say, I am completely sure that this incident is at least partially fake as of it's ending.
but that doesn't mean such an event didn't happen, something like this prolly happened, but anon made it go from 1 to a 100 for the fun, maybe he did end with kansai, had a friendship harem with the girls, failed at being the wizard Emporer or whatever, but he totally faked some of the events as something else to make it into his own fantasy-based visual novel-esque plot, that doesn't make an asshole tho, this was written in an anon board, I would have exaggerated some things in the story if happened to me too lol, in the end, who cares, this gave fucking heart-thumping feels and kept me on my edge all the time, worth my time, so, thank you anon, for sharing your story which made this manga possible.
TL;dr: the story might not have been the truest one on the internet, but who gives a fuck, enabled the author to make a nice slice-of-life manga which gave me the feels anyway, so thank you anon, bang the kansai hard and breed like catholic rabbits you bastard
