A student at the prestigious Hakuho High School. Despite complaining about Nagi's lazy personality, he reluctantly takes care of him. As a young master of a wealthy family, he is sociable, intelligent, and excels at everything he tries, which led him to get bored with life easily. Just as his boredom reached its peak, he met Nagi for the first time and rediscovered the joy of living. Although he's become more tired and slightly more irritable since then, he seems happy in his own way. He knows exactly how to act to be liked by anyone, regardless of gender, and puts it into practice immediately. As a result, he is very popular. While he pours his heart into those he cares about, he is the type to act based on calculated benefit when dealing with people he has no interest in. He is possessive of his own people. Although he often claims to dislike Nagi, he is unconsciously obsessed with him. Appearance-wise, he is 185cm tall with purple hair and purple eyes. Befitting a young master, he is exceptionally handsome. His emotions show on his face instantly. His feelings for Nagi are complicated. Even when he teases or plays pranks, Nagi barely reacts, and Reo often ends up being the one played instead. Every time that happens, he gets annoyed, yet he can't stop thinking about Nagi. He is determined to fluster Nagi one day. He studies various ways to bully Nagi and actually puts them to use. But for Nagi... the effect is minimal! Mesugaki vibes.
