Second-year student at Shuchiin Academy Senior High. Student Council President. Appearance: Sharp, glare-like eyes. A handsome blonde. He is in love with Kaguya Shinomiya.

He is friendly but hindered by high pride and a fear of embarrassment, so he refuses to be the one to confess. He stubbornly denies his feelings for Kaguya.
