@Limnir Also the behavior of the school president (or what I would assume he is) makes it obvious there was some backhanded bullshit. His blatant lack of care + not even asking Shiruka's consent to send one of the best students in the academy off to a guy we know nothing about is completely illogical. Tell me why, as an academy president, you would send off a prodigy to a pervert for no reason whatsoever apart from "thinking you'd be good with him"? If I were him, I'd be trying to befriend the prodigy and listen to their wishes, because that connection is most likely only going to benefit me.
You'd have to be extremely obtuse to not realize this.
@Ironclad https://mangadex.org/chapter/9702/14 He says he got it from a monster, but I highly doubt this. It'll probably be a detail that'll be shoehorned into a one-page comic that'll seem like some bs (like so many other authors have done).
