Ayakashi Triangle Vol. 1

Teenager Kazamaki Matsuri has long been part of an elite force of ninja exorcists, tasked with fighting malicious ayakashi spirits who threaten Japan--especially those after his childhood friend, the spirit medium Kanade Suzu. As he fiercely protects her, and his relationship with her blooms from friendship into something more, a powerful cat ayakashi vows to get between the lovebirds: by casting a forbidden spell that turns Matsuri into a woman! With no apparent way to undo the spell, Matsuri must continue battling ayakashi--and go back to school--in this new feminine body until he can find a way to turn back.
