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?
a ray of light will always shine 
in the darkly clouded sky.
wird ein Lichtstrahl die
dunklen Wolken durchbrechen.

dans les cieux les plus noirs.
una piccola luce
potrà brillare sulle nuvole nere.
uma pequena luz vai brilhar 
no céu escuro e nublado.
