Ayakashi Triangle - S01

Ayakashi are strange supernatural creatures that most people cannot see. While most of them are harmless, some attack humans to devour their life force. Exorcist ninjas are given the job of protecting people from these spiteful spirits. Matsuri Kazamaki is a young exorcist ninja born into a prestigious clan. His childhood friend, Suzu Kanade, is an ayakashi medium, someone with immense vitality that attracts ayakashi. Matsuri sees all ayakashi as a threat and wants to keep Suzu as far from them as possible, but this clashes with her wish to stay close to them. One day, the two encounter Shirogane, the "King of Ayakashi," who is determined to consume Suzu. Just as she is about to be eaten, Matsuri comes to her rescue and manages to seal the ayakashi's powers, but not before Shirogane gets revenge by turning him into a girl. Until he finds a way to change back, Matsuri has to adjust to his new, peculiar lifestyle while fighting hostile ayakashi. On top of that, Suzu is now unsure about her feelings for Matsuri, which pushes their relationship further into a state of ambiguity.
