Katsuya is a handsome man. (uh, not in the sense of his beauty, I mean that I like him for his character, he is almost like MC) eh, if only he were not on Kenichi's team... but (!!!!) there should be ONE sultan in the harem. and all the WA girls should belong to MC.
Let Katsuya find himself another girl somewhere - I will not be against it. but let him not reach for the WA girls.
but nevertheless Katsuya is much more restrained and looks more like an adult man and not an overgrown boy like Kenichi. he even has a healthy sense of humor. personally, I do not regret that MC gave him a little positive karma.
and in general, not long ago I had a weak but persistent suspicion that Katsuya could go under the MC team. let's call it intuition. at least based on the fact that he joined in MC's joke about Yoko, when the principal called MC to him, and MC said that what he did to Yoko he will not do again, unless she herself asks or deserves it - and Katsuya joked right there that Yoko will not keep her waiting long. This is a sign that the influence on Katsuya has moved from Kenichi to MC.

Let's fantasize a little on the topic of "what if". Let's say MC cleared his father's name, somehow transferred the ownership of the academy to his name. He achieved a lot. But he ended up with a large harem of girls who need to be taken care of not only with intrauterine infusions but also with financial support. Under the academy, as we remember, there is a chemical laboratory. So, how could MC have enough money to support his girls? As I understand it, after the fall of Hiroshima (Shirohima-Hiroshima, what the hell difference does it make? haha) Zaibatsu will pass into the hands of Kayane - Kenichi will have no influence, unless he manages to avoid going to prison for illegally entering and robbing Musashima's property and removing material assets and documents from there. So, how can MC have enough money? partnership with Zaibatsu?
