Seven years ago, Yuuto Amakawa’s parents died leaving him living alone without a single relative. He is the last descendant of the Amakawa Clan, one of 12 ancient demon-slayer families.
Ever since the accident, his childhood friend, Rinko Kuzaki, has woken him up, cooked for him and generally taken care of him. The only thing he has from any relative is a mysterious charm, a red ball, given to him by his grandparents as an omamori or a good luck charm.
Things change on Yuuto’s 16th birthday when his protective charm stops working. A number of evil spirits want to kill him, fortunately for Yuuto a cat spirit-samurai, and demon huntress, named Himari appears to protect him.
Rinko is not happy with the situation, because Himari is gorgeous, and she is able to beat Rinko in all of the sports that Rinko usually excels in. This is how Rinko starts to grow in frustration and takes out her anger against Yuuto.
Himari really likes Yuuto and tries to make him put his eyes on her at any cost. But there is only one small problem, Yuuto has a severe allergic reaction to cats. This causes his eyes to water and his nose to run.
Yuuto’s life becomes more complicated when he discovers that he can wield the “hikariwatashi”, or Light Ferry, the Amakawa Clan’s ancient demon-slaying power that is both feared by demons and spirits due to its very powerful nature and coveted by members of the other demon-slaying families.
