"Angelique: Twin Collection" OVA 8 episodes
It's an 8-episode OVA with a music video of a bishie for opening and ending. Some of the clips are in YT except the MV's for Marcel, Zephel, Sei-Lan, Ernst and Mel. They all sounded the same to me. I guess I"ll have to listen to all the songs in a non-stop loop for me to distinguish the melodies. It doesn't help that "Vampire Knight" theme is stucked in my head. Offhand I could easily remember Arios' mafia-looking video and Olivie's dance moves.
