He's one of Kaguya's half-brothers—born to her father's second wife—and ranks as the third son in the family. Kaguya doesn't mince words about him: she thinks he's a pretty terrible person. That said, she does respect one thing about him: he never breaks a promise, and she acknowledges that integrity even if she despises almost everything else about him.
He harbors real contempt for both the Hayasakas and the Shijos, viewing them as traitors to the family. It's the kind of deep-seated disdain that clearly runs through the whole household dynamic.
What's interesting about him is how he functions as a kind of dark mirror to Kaguya. Fans often note that he represents what she could have become if she'd never joined the student council—basically, a product of the Shinomiya family's ruthlessness and isolation without anything to pull her toward genuine human connection. He embodies all those cutthroat tendencies without the redemption.
