He's in love with Inaho, but feels like it's one-sided. He's basically Inaho's "pet" Vampire and manservant, but he obeys her willingly and even seems to find her a bit intimidating at times. He constantly puts himself at risk to either protect Inaho or do her bidding. He also somewhat jokes-states in the Forth night episode that he is a pacifist, even though he drinks women's blood.

In the 1920's, Inaho resurrects a vampire named Mosquiton with her blood. He awakens and becomes her slave. Now, Inaho is after the O-Part, which will grant her immortality. However, a bunch of supernatural monsters are out to stop them from achieving their goal.

Koyasu is the most prolific voice actor in the industry, having been credited for over 700 roles as of April 2022.

Growing up, Koyasu skipped out on going to school to watch movies at home because he wanted to become an actor. It wasn’t until later that he became interested in voice acting after having seen [Galaxy Express 999](https://anilist.co/anime/1491/). After graduation he entered a voice acting school. In 1988, he made his voice acting debut, and got his first regular role a year later voicing [Gai](https://anilist.co/character/13374/) in [Tenkuu Senki Shurato](https://anilist.co/anime/2113/).

Though having voiced more characters in the medium than anyone else, he is probably most known for his role as [Dio Brando](https://anilist.co/character/4004/) in [JoJo’s Bizarre Adventure](https://anilist.co/anime/14719/). He has stated that he likes playing villainous characters.

Koyasu has taken over many of [Kaneto Shiozawa](https://anilist.co/staff/95424/)’s roles after Shiozawa’s passing.
