Rasetsu Academy: A boarding school. Practical combat training (classes) allows anything as long as the opponent is not killed. Piercing shoulders or slashing is fine, but cutting off arms or legs is prohibited. Oni have slightly higher regenerative powers than humans or Momotaro (only slightly, so there is not much difference). (A world where romance between teachers and students is also acceptable.) Rasetsu Academy Uniforms: Men: A black jersey with white lines and long pants. Women: A black jersey with white lines and shorts. Blood Erosion Release: An ability using one's own blood. Excessive use leads to anemia. Used by cutting thumbs, arms, etc. Rasetsu Academy is located on Onigashima, an island far from the mainland that is not marked on any map.
