Stargazing: Shalala ~Watashi ni Kureta Mono~ - Fukuen Misato, Chiba Saeko, Koyama Kimiko, Kugimiya Rie, Mizuki Nana
Monsters meet human in the strange adventures of Rosario to Vampire. From my own personal viewing, I wasn't a big fan of the simplistic harem that ran too many of the regular tropes. However, the show did feature a Kugimiya Rie character that I won't soon forget.
Much like what I do with many shows, I can still walk away from a show I dislike with some new music if the soundtrack is sound. Coming from this show's rather large set of character albums, this track combines the talent of all of well-known seiyu in one neat package.
