A bat who acts like a narrator saying things like how long a battle takes place and occasionally covering up fanservice.  It appears in the manga's sequel, Rosario + Vampire II. He seems to be Shuzen Kokoa's servant.  His special ability is to turn into any kind of melee weapon, his only draw back is he weighs 100 kg.  He has a tendency for saying 'weeee!' after any commentary or plain statement.

By a bizzare coincidence, Tsukune Aono has accidentally gotten himself admitted to a youkai academy, a school attended by monsters. Just when he thinks he'll run away from there, he meets the beautiful girl Moka and his mood turns ultra happy. However, she transforms into her true form when the rosary on her chest is taken off, she's a super vampire!

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.

Average human teenage boy Tsukune accidentally enrolls at a boarding school for monsters--no, not jocks and popular kids, but bona fide werewolves, witches, and unnameables out of his wildest nightmares! 
On the plus side, all the girls have a monster crush on him. On the negative side, all the boys are so jealous they want to kill him! And so do the girls he spurns because he only has eyes for one of them--the far-from-average vampire Moka. 
On the plus side, Moka only has glowing red eyes for Tsukune. On the O-negative side, she also has a burning, unquenchable thirst for his blood...
