A real man doesn't chase. But this simple fact is sometimes unknown. And thus, Takuto Higashi develops a prototype of an AI girlfriend who can give the boost a man needs—the Sigma Confidence. He has another reason, though.

However, he dies and goes to another world with his $50 AI girlfriend before he can spend all the money he has accumulated. But it’s alright, because he has the Sigma Confidence, the pirated knowledge of an AI, and a new, otherworldly dream.

So he has no magic. Only edginess, against overpowered SkyKnights.
