Age: 19 Gender: Male Characterized by pale purple hair with light blue streaks, golden eyes, and a cat-like mouth. Rui's streaks are natural, as seen in his childhood self from 10 years ago. Unlike other characters, the corners of his eyes are reddish; this is also visible in his childhood appearance, suggesting it is natural rather than makeup. He is firmly established as a weirdo at school, so his appearance is rarely commented on, though he did mention during an early Valentine's Day live that there were somehow chocolates in his locker. He has a piercing in his right ear and often wears elaborate earrings as accessories in his card outfits. His casual clothes are bizarre to the point of being considered a fashion disaster. His 2nd-year casual outfit, featuring a jacket and shirt with indescribable patterns, is frequently mocked. At Kamiyama High, he and Tsukasa are known as the eccentric duo, the "Wunderkind One-Two Finish." In a 1st-anniversary Q&A, it was revealed Tsukasa is #1 and Rui is #2. In a Wonder Show broadcast Q&A, to the question "How many times a week do you hear noises or explosions at Kamiyama High?", the answer was "At least once a day. I wonder who it could be..." While he may seem like a complete 4D character, he actually possesses sharp insight into people's true intentions and generally maintains a detached, observant attitude. However, he is infinitely kind to those he is close to, showing a gentle and soft personality with rich emotional expression. While he has a mature side that worries about and advises his friends, he also shows his age by playing mischievous pranks or acting sly. He used to have a crush on Guest. However, due to Miru Hariki, he has come to like Miru. Now he doesn't even know who he truly likes. Kamiyama High, 3rd Year, Class C.
