True Smile ~Peace and Anxiety~.A mysterious assassin named Azenda arrives on earth seeking revenge with Yami. Mea questions her regarding Yami, but the master believes Azenda could help revert Yami into an assassin and kill Rito. Meanwhile, Mikan wakes up to find Celine missing. She hears moaning noises through Rito's room and blasts into his room only to find him playing a game with Momo and Celine. Momo tries to reassure Mikan that she's only supporting Lala's love, but Mikan does not believe it. In the shower, Momo wonders who destroyed her barrier and relates it to fact that someone is targeting Rito and Yami. After another disastrous day at school involving Oshizu using her telekinetic powers on Haruna, Yami feels lonely and visits Mikan. As they both eat Taiyaki, Yami hears Mikan express her concerns about Momo. Mikan gives Yami a Taiyaki keychain and shows her pair to symbolize their friendship. Yami happily accepts. The following night, Rito finds Yami. Rito is happy that she talked to Mikan as Mikan usually feels depressed. Yami feels strange about happiness per Mea's words. Rito assures Yami that she should do what she wants. Suddenly, Azenda appears and confronts Yami. Having observed Yami earlier, she uses Mikan as a marionette to defend herself and attack Yami. Being friends, Yami chooses not to attack, allowing Azenda to easily defeat Yami. Next, Mikan tackles Yami and does obscene gestures, setting them in a perfect position for Azenda to kill them both. Azenda rambles about how she lost her pride after Yami defeated her and uses this chance to get even. Rito tries to stop Azenda explaining that Yami and Mikan do not deserve this, but Azenda chooses to kill Rito instead. At the finale, Momo intercepts her plant monsters and defeats Azenda. Mea sees the fight from a distance and is unsatisfied that Yami did not attack Azenda.
