Everypony in town is aware of Octavia's talent in playing the cello. But when Octavia is asked about how she learned to play the violin with almost as much talent, she starts describing her first violin lessons from the famous violinist Otoya Kurenai.
Unfortunately, those memories weren't very fond ones. Especially when they involve vampiric monsters attacking.
A crossover with Kamen Rider Kiva (a show created by Toei company) and My Little Pony: Friendship is Magic (a show made by Hasbro).
Rated T for Teen, because some of the monsters mentioned above get violent.
