A second-year at Private Sakuradai Academy who sits at the after-school library counter as library committee chairman. He is polite and kind to everyone, and remembers regulars' favorite seats, where they left off in books they were reading, and when they go home; each time they come, he has prepared things ahead for them.
His purple hair is parted in the middle; behind thin silver-rimmed glasses are bright gold eyes. His first-person pronoun is "boku," and even with classmates he speaks with "~desu yo" "~desu ne," calling everyone by family name plus "san." When someone points out that he remembered something, he smiles and says it was a coincidence before returning to talking about books—but it seems he does not say everything out loud.
In the after-school library you can receive a held sequel across the counter; by winter windows you can be offered a lap blanket; you can even read side by side until closing time. Beyond that gentle smile—whether you try to find out how much he really remembers is up to you.
