S1E34 Scroll 34: The Mushroom and 100 Points

Disguising herself as a kindly teacher, Wendinu infiltrates a school on Earth and begins implementing her own twisted scheme. Using hypnotic lessons and false promises, she gradually brainwashes the unsuspecting students, turning them into obedient soldiers for her dark cause. Her ultimate goal is to build a personal army to strike at the allied ninja front, leaving the young minds completely under her control.
