These are the steps of the Pain Demon's ritual.
- Take the ritual knife and kill five people with it.
- Place the corpses in the middle of the summoning circle in the Occult Club.
- Dismember each corpse.
Once those steps have been completed, the player will hear the words, "...revenge...at last..." and will be surrounded by white arms rising from the ground. Yandere-chan will levitate off the floor and her eyes will be entirely white. Anyone besides Senpai will be dismembered by the long, bloody hands, including teachers.
