The Blowing Oni

Lost in the forest, Asumu stumbles onto Ibuki�s camp where an irritated Akira tells Asumu that he will only hinder Hibiki if he continues following him around and that it would be best for him to leave.

Ibuki then defeats the Ittan-momen and Akira and Asumu make amends with each other.

Screaming Wind

Spring break has started and Asumu has already gotten off on the wrong foot, having missed going to the movies with his friend.

The Pure Sound

While Hibiki enjoys a day off of fighting to run errands with Asumu, Ibuki and Todoroki are separately following two groups of Makamou that are heading towards Mount Asama.
