An eccentric young man who is usually seen wearing a space helmet. Despite his eccentrics, he seems to be part of a good family and acts like a samurai when doing student council work, often adding “-dono” to people’s names. He’s a straight A student in everything but sports, but his airheadedness often causes trouble. He’s a beauty under his helmet with a face often compared to Princess Kaguya, garnering a radical and cutthroat fan club, some of whom call him “Princess”.
