Lost Universe Season 1 Episode 6

Fallen Angels Run

Highball is a ""female only"" nursing school ship. Kain, disguised as a woman, and Millie are among the students on a mission to protect the two major student groups who are in conflict with each other. On the day of the school's graduation performance exam, one of the students is injured as a result of the two fighting groups. That provokes Kain into lecturing them, which moves the students and helps them regain the spirit of fellowship.
