Ayakashi Triangle S01

Matsuri Kazamaki and Suzu Kanade are childhood friends and both have the ability to see Ayakashi, yōkai that feed on life force. However, in high school, their friendship deteriorates. As Suzu's one-sided feelings grow stronger, their differing views on Ayakashi also grow further apart: Matsuri sees all Ayakashi as a threat to his friend, while Suzu is enamored with them despite the danger they pose. When the two meet a talking white cat named Shirogane, they are unaware that he is actually a 400-year-old Ayakashi known as the "King of Ayakashi". Shirogane intends to consume Suzu's life force, but Matsuri intervenes, attempting to save him and seal away Shirogane's powers. However, the Ayakashi uses a jutsu and turns Matsuri into a girl.
