桐坂 理人

The middle child of the Kirisaka family.

Kagokita High School 3rd year. He believed he was the twin brother of Sora, as his birthday is only one day after hers. His name is difficult to say, so his relatives call him "Ri" for short. He is always in a bad mood and has a bad mouth, so he often argues with Sora.

He is playing the drums in the light music club.
