Ika Musume seems to regard him mostly with disinterest and appears to have a low opinion of him, though she frequently plays with him anyway. Over the course of the series, however, this view is lightened to the point that Ika comes to view him as a friend.
Takeru is a little boy. He has black spiky hair and black eyes. He typically wears a green t-shirt and brown shorts.
Takeru acts very childish compared to his sisters, and actually tries to befriend Ika.
- Takeru is the only one in the Aizawa family to not wear any kind of long-sleeve pants.
