He is a bit naive and very innocent towards girls. His affection towards Kana will often make him do regrettable things but because of them he has had the opportunity to become closer with the family and visits them often. Chiaki has come to associate him as a father figure and will often place herself on his lap when she seeks fatherly affection or to complete the family experience. He is the only person who does not know that Tōma is actually a girl.
