Heisuke is smart and gets excellent grades. However, when his favorite food, tofu, is involved, he becomes a problem child who unconsciously drags everyone into his antics and causes trouble

He is not only enthusiastic about eating tofu but also has extensive knowledge about it, is devoted to making tofu dishes, and spends his time researching and making tofu
His signature weapon is a suntetsu (a concealed weapon)
In the Gunpowder Committee he belongs to, he holds tofu parties and often chases his roommate Kanemon around with tofu. The tofu dishes Heisuke serves are so plentiful that one person can't possibly finish them, leading other fifth-years to call it "Tofu Hell" (though the taste itself is reportedly very delicious)

He always carries freeze-dried tofu in his pocket
He loves tofu so much that he often loses his composure
He claims he can hear the voice of tofu

His usual offbeat remarks and his habit of immediately voicing or acting on his thoughts and feelings without malice often anger others or cause those around him to be exasperated

He is also very sensitive to criticism and has a delicate side, getting easily discouraged by trivial matters
A natural airhead
