Ayakashi Triangle

Matsuri Kazamaki, a young exorcist ninja from a prestigious clan, is tasked with protecting people from ayakashi, supernatural creatures invisible to most humans. His childhood friend Suzu Kanade, an ayakashi medium, has immense vitality that attracts these spirits. When Matsuri's attempt to keep Suzu safe clashes with her desire to interact with the ayakashi, their complicated relationship deepens. This dynamic is complicated further when Shirogane, the "King of Ayakashi," consumes Suzu, but Matsuri is able to seal the creature's powers, although not before being turned into a girl as revenge.
