It's been technically hinted several times in the story, when something was mentioned about his past, but during 2007 to 2009, he was indirectly in charge of his family's conglomerate's affair's, cause the finance crisis happened directly a month afterwards when his 'family died'. Around that time, he slowly gained his skillset about his manipulation abilities. As for the other thing, he's naturally very gifted, since birth. As Arisu mentions, a "genius" or how Atsuomi says, "a prodigy." The way he absorbs knowledge is different than other people. Of course, things like observation and all come from somewhere else, but he's someone who studied very much, since he's not very trusting and did not want anyone to ruin his parent's legacy. There are some psychological aspects mentioned, like in Chapter 45, or theoretical stuff regarding the engineering stuff, which was especially mentioned in the Chairman Sakayanagi Chapter. Hopefully, these things were so far okay. I was wondering often whether to include that or not, since it's not common for the high schooler's, but well, I don't dislike writing it, so I include these kinds of things. Although the latter chapters now should become slightly more philosophical. They'll probably contain things from Dante Alighieri, Nietzsche, Plato, Socrates, Søren Kierkegaard, though, I've no plan, still. Anyhow, I hope these things that I incorporated so far were not boring with the engineering stuff or the other stuff.
