A salary man for The Fujido Group and Chiharu's cousin. He enjoys teasing Kazuki. Kaouru is a favorite among other employees as he is always polite to them and speaks to Chiharu on their behalf. Growing up watching his mother's failed relationships ( which in turn she blames him) Kaouru becomes one to always put his pride before anything else, however that all changes when he meets Daigou Mikihisa.
