Shortly after this, SUNNY leaves WHITE SPACE and HEADSPACE behind as he is ready to face reality once more. Once SUNNY and MARI finish their duet, OMORI accepts defeat and embraces SUNNY with a hug, vanishing from WHITE SPACE. He performs the duet recital with MARI, remembering the good times he's spent with MARI and his friends during his youth. If SUNNY chooses to continue, he will get back up, readying himself to play his violin with renewed vigor.

Sunny refuses to give up against Omori during their final battle. Selecting either option will lead to an ending that changes the title screen, as well as earning an achievement in the aftermath. There are only two possible outcomes if the player chooses either one of the two options after losing to OMORI the first time around: CONTINUE and DO NOT CONTINUE. OMORI ends up overwhelming SUNNY by constantly reminding him of what he had done to MARI and that he doesn't deserve forgiveness for his actions.

The two end up battling for control of SUNNY's mind. SUNNY is then transported into WHITE SPACE again for a final showdown against OMORI. He eventually breaks down in tears over getting to mourn his older sister's death.
