コープスパーティー
The opening theme for "Corpse Party: Sweet Sachiko's Hysteric Birthday Bash" is called "Limited Love" by Imai, and the ending theme is "Tsukigen" by ARTERY VEIN. An insert song, "Hanabi", sung by Yumi Hara, plays at the final scene where Sachiko's birthday has ended and she seemed to have only a brief memory of it, before screaming in agony and reverting to her malicious self.
