    A university student who meets Serizawa while browsing at the bookstore. Despite being younger, he is very tall and has an imposing, intimidating presence, leading Serizawa to call him "Takeuchi" after the actor Takeuchi Riki. However, he is actually a sweet, shy, and considerate boy. As he and Serizawa grow closer, he becomes somewhat clingy but also doting and adoring.
