鍛える夏

ヒビキがトドロキに太鼓を教えている。夏になると強力になる魔化魍に対抗するために更なる鍛えに入っているのだ。ただ、ヒビキのあまりの熱心さに困惑するトドロキ……。一方明日夢は吹奏楽部に入ったが自分のやりたいドラムができず、練習に実が入らない。

Hibiki takes Todoroki to his mountain top training temple to teach him how to play the taiko. Unfortunately, the training seems to be too intense for him. Asumu is assigned the whistle in his high school's brass band and is not too pleased with not having the chance to play the drums.
