It's too soon to celebrate summer vacation for Mumei and his classmates. Something seems off about Miss Ou. With the moon creeping ever closer, Mumei learns that even his Shokatsu Technique isn't invincible.  With the Earth and Haku's life on the line, one final test will put Mumei and the others through the ringer. Is there really anything the Shokatsu Technique can't solve?
