Hell Teacher: Jigoku Sensei Nube S01 E11 Demon Hand vs Fire Tail Jutsu

"Can you protect them all?"

Tamamo, the fox demon Nube vanquished for trying to take Hiroshi's skull, reappears one day at Domori Elementary. When a furious Nube confronts him, Tamamo says he is no longer interested in Hiroshi and declares a temporary truce. However, he suddenly attacks the students of Class 5-3. It soon becomes apparent that Tamamo's true target is not the students, but Nube's special power.
