Go Kato

Go Kato is the lead singer of "Bee Hive" and a student at the university. He lives with his little brother Hashizo in a small apartment and is trying to become a professional and successful musician. He is cocky but charming and has a reputation of being a playboy. However, when he falls in love with Yakko, he becomes totally devoted to her, although he has to struggle with juggling his musical career and romantic relationship.
Even though Isao Sasaki is a singer, Go's songs are actually sung by Ai Takano in the anime.
