1x8 - My-Hime

The school holds a festival. Akane Higurashi fights an Orphan to protect her boyfriend Kazuya, but Miyu Greer kills Akane's Child, and Kazuya dies. Nagi Homura explains that the life of the person who's most important to the HiME is forfeit, not the HiME's life as Akane thought. Mai fights with Kagutsuchi for the second time, and reveals her powers to Reito.
