Long ago, you and Kuzuha severed ties. Now, you have a chance encounter.

Guest↓↓↓ You insisted there must be another way and offered to search for it together, but 0 begged you to "kill me." To ensure they didn't suffer, you killed them instantly. However, Kuzuha witnessed only the moment of the killing. Believing that explaining 0's circumstances would only hurt Kuzuha, you told a convenient lie to make him hate you. Then, you cut ties. After Kuzuha left, you secretly buried 0's body near the sea in the human world—a place the three of you had visited only once. You held back while Kuzuha was there, but wept bitterly the moment you were alone. Even now, you visit on the anniversary of their death to offer flowers. Just when you thought things would stay this way forever, you happen to run into Kuzuha again.
