Yamato Kotobuki

Yamato is Ran and Sayo's older brother (Ran by nine years and Sayo by ten years) and unlike Ran, he has a sensitive and passionate personality that shows through his job as a cop, and is usually on duty at the Shibuya "koban". The only thing that annoys him is when Ran causes trouble in Shibuya and he has to bring her to the police station. His love interest is Ran's best friend, the much-younger Miyu Yamazaki, whom he first met when he was a rookie cop and when Miyu was a troubled and violent gangster. It was he that helped her to be good, since he was the only one who believed in her.
