Kaoru is a young boy, around ten years old. He has mid-length dark hair with bangs between his eyes and next to his ears. He usually wears a white t-shirt and blue shorts.
Kaoru tends to be overprotective of his mother, being distrustful of other males who come near her, warning them not to ingratiate themselves with her.
The Lost Substitute Shinigami arc
Kaoru wakes up to hearing his mother yelling at Ichigo. He walks barefoot into her office, despite not being allowed to do so, and complains that he is hungry. When he sees Ichigo in the office, he asks him what he is doing there, and tells him not to make a move on his mother just because of her looks. He ends his argument with a raspberry before Ikumi takes him out of the room.
When Ichigo returns to the shop late one evening, Kaoru eavesdrops on his conversation with Ikumi. He hears her complaining about Ichigo missing work and asking for more time off. Kaoru continues to listen as his mother pleads with Ichigo to trust and confide in her more.
