S1·E9 End of a Promise

Aono has come to kill Matsuri in an abandoned part of town and a one-sided battle ensues with Aono attacking while Matsuri runs for her life. In the end, Aono cannot bring herself to kill Matsuri and leaves afterwards. After suffering another mental attack, Yorito is brought to Mana's place to keep him safe from Aono who later comes looking for him; Mana manages to get her to leave. Later, Matsuri runs into Takeshi again who once again tries to kill Matsuri and nearly succeeds, but Mayuko intervenes in the end and saves her life.
