A cold and reserved boy who is Anzu's first romance candidate. He is popular among women due to his good looks but tends to avoid them, rejecting any romantic proposals outright. He meets Anzu where she accidentally bumps into him and breaks his phone. Due to Riri's meddling, his house is flooded and he has to live with Anzu early in the story.
[Spoiler] It is later revealed that before transferring schools he was a warm and caring person who could "befriend anyone", indicating that his cold appearance is a facade. His personality changed drastically after being repeatedly stalked by an older woman he had helped once, to the point where he was forced to transfer from his house and school to be away from her and his strict father who blamed him for the situation. He then became lonely and distant after living alone. In an effort to distance himself from women's attention, he often wears hats in public and experiences panic attacks if left alone with them due to traumatic memories. He finally realizes his hidden feelings for Anzu after she helps him many times, considering her to be his savior. [/Spoiler]
