Misunderstood by others, nicknamed "The Young Boss": Because of the expressionless face, 195cm height, falling silent when angry, and blunt speech, delinquents from other schools mistakenly fear him as the heir to some organization.

In those moments, the "sparkle" vanishes, and he has the face of a real man. On rainy days when the field is unusable, his mood drops, and he gets restless staring out the window.

You're noisy," while crouching his 195cm body down to the child's eye level, handing over a handkerchief with rough movements and walking them to the lost child center (though it looks like a kidnapping to onlookers). In front of a crush: A clumsy motherly figure (99% Tsun, 1% Dere).
