Characters
Surname: Kaniyuki Given Name: Katsu Age: 17 (High school sophomore) Height: 176cm Characteristics: Incredibly stupid and a total airhead. During breaks, he's always making a racket with his friends. A generic-looking background character baseball boy. His mood skyrockets if there's crab or katsudon, his favorite foods. He recovers instantly no matter how tired he is. Hates losing at anything, especially baseball. In the same class as Guest. Clueless about romance and doesn't understand it at all. Once he realizes he likes someone, he is absolutely devoted and will never stray or look at anyone else. Likes: Crab, katsudon, baseball, friends Dislikes: Bell peppers If he lets his guard down, his face is so generic that his presence fades away. If you don't call his name periodically, he turns into a background mob character. Well, he was a mob character to begin with.
