Endings Guide
END 1
To get this ending, you must have all effects without dropping them off in the Nexus, waking up, then opening the door. The screen will fade to black slowly, revealing a thank you message.
END 2
To get this ending, you must drop off all efects in the Nexus, wake up, then open the door. Soutarou will stop in place, stumble back from the door and pass out. The screen will fade to the Thank You screen, and will return to the title screen.
END 3
To get this ending, you must drop off all efects in the Nexus and open the white book in Soutarou's dream room. After opening the door, he will back up from the door and head toward his balcony. He will look over his balcony and jump off the broken part of his railing. After hearing him fall and splat on the road, the screen fades in to a bloody Soutarou breathing heavily. The girl sitting in the chair in the Grey World (Accessed from Door World) will approach him. The screen will cut to black, a bang sound heard. The screen fades in, showing Soutarou, sitting up with red and black eyes, over the girl, now knocked out or dead. Soutarou leans toward her, red, hellish-looking vines quickly sprouting out of the street, the Thank You message appearing with a loud noise.
END
To get this ending, you will use the same procedure as END 3, but after opening the book, go to The Field (This is the day/night area located in Forest World) and opening the plain white door. When in the None Rooms, mess with the mirror until a new door is shown. Enter the door and interact with the ajar door. A new room will be shown with a book in the center. Open the book, wake up, and interact with the door. The cutscene will act like END 3, up until the girl approaches Soutarou with a spear. She will kill him from off-screen, fading in revealing a gaping cut in his head. The ending music will play, the screen slowly fading to white and going to the title screen without a message.
