This is the first available ending of the game. It is only available once you have collected all 24 effects.
Sabitsuki will be shown outside, on a rooftop with a railing. Then the screen fades to black as a faint "thump" is heard. Two blood spots appear and two black-haired girls are there as well.
Collect all 24 effects (25 including the instructions). Then go outside.
- It is speculated that Sabitsuki committed suicide by jumping off.
