Saki's step-brother and a second-year high school student. He came into her life when his parents remarried, making their relationship relatively new compared to lifelong siblings.
He's the quiet type—not unfriendly exactly, just sort of detached from the people around him. His real passion is books. Like, genuinely obsessed with them. He reads constantly and has basically amassed a library's worth of titles. Fans often joke that he'd rather be lost in a novel than dealing with actual people, which. fair.
