ついにはじまったカルデアビーチバレー大会。
やる気と遊び心、そして筋力を持てあました彼らは
堰を切ったようにチームを組んだ。

だが筋肉といえばアレ。
アレといえば微笑みマッスル。

テクニック派のアレキ＆侠客の相手は、
これまであらゆるボールを弾き返し、
顔面レシーブさえいとわない超強力レシーバー。

打てば打つほど強くなる壁相手に、
果たして勝ち目はあるのだろうか―――！

Chaldea's beach volleyball tournament has finally commenced.
With much enthusiasm, playfulness, and MUSCLE, they excitedly set up in teams.

But when one thinks of muscle, HE would be involved.
When you think of HIM, one would think of his muscled smile.

Alex the technician and his outlaw teammate face an opponent who returns every volley: a super powerful receiver who doesn't flinch even after tanking the ball with his face.

Is there a chance of winning against a wall that gets stronger every time it gets hit!?
