Birthday: February 1

Touma is a boy in Futaba's year, making his first appearance in Chapter 12. He initially has a very bad impression of Futaba, during which she trips and ends up accidentally groping him. However, he eventually softens up to her when he notices how remorseful she feels about the incident. Due to his earnest appearance, his intentions are often misunderstood, usually causing Kou to get jealous over his interaction with Futaba. His friends call him "Goodie-goodie" and "Hasabe" due to his straight-laced and honest behavior. He has a piercing on his left ear and likes wombats.

After confessing his love to Futaba, saying that he'll never give up, they start going out. He is well aware that she liked Kou, but tells her that he'll make her fall in love with him no matter what. They broke up when Yoshioka comes to terms that she will never love anyone else but Kou.
