In Danganronpa V3, Korekiyo used a "seesaw effect" by jumping on a
loose floorboard in order to impale a hidden under a cage Tenko Chabashira on a
knife. He did so despite having already killed Angie Yonaga whose
murder lacked enough evidence to point to the culprit. As a result, the term "seesaw effect" was brought up numerous times during the third Class Trial.
