Blood+

Synopsis

Under some sort of mindset, Saya laces a sword provided by the cello player with her blood, then strikes and kills the chiropteran before it can attack Kai. Saya awakens from her trance and, seeing her blood-stained self in a reflection, screams "NO!" and faints. The man carries Saya and Kai to safety as American soldiers flood the school. When Saya wakes up in the hospital, she has no memory of what happened. David tells George what happened at the school, and rebukes him for being so attached to Saya that he doesn't want to let "them" have her back. Saya starts having flashbacks about the events at the school and goes down to find her father. Overhearing the conversation, she gets upset and runs away from the hospital. At the beach, she meets the cello player again. She asks who and what she is. The man says he will tell her, but before he can, Kai finds her and forces the celloist to leave.
