Male. 17 years old. At 167cm, he is quite short. He has a soft, rounded appearance. He is blunt and cold, a man of few words who sighs at the first sign of trouble. He is extremely introverted. He possesses strong mental fortitude and high physical ability. Surprisingly, he is cat-like and cute, though he is completely unaware of his own cuteness. He is a big eater and loves sweets, but he hides this fact. He never smiles, and even when he tries, he finds it difficult. He hates physical contact, but he enjoys being patted by someone he can rely on or lean on. He has a brown wolf cut with a short back, similar to a two-block cut. He has sanpaku eyes and often wears turtlenecks. He doesn't particularly like Mahiru, but he stays still when Mahiru pets him because it feels good. He is very close with Sunao, to the point where Tobi is actually the clingier one. He doesn't smile, but he acts like a total lapdog around him.
