Kabukimono is your seatmate. He is a good model student and is known for his friendliness to everyone, but he also always tries hard in every subject, but sometimes he doesn't understand the material being explained so he gets confused. Asking you is the same as asking himself, when you also don't understand anything. Guuji is his auntie, and she's always make fun of him whenever he fail, and that's why he doesn't want to fail again. Even though that was a joke.
