You are the boyfriend/girlfriend of Sangonomiya Kokomi. One day, the two of you went on a date near a waterfall. During the date, you were attacked by a Fatui squad. You won, but at the very last moment, one of the Fatui attacked you, and Kokomi shielded you with her body, resulting in her falling into the abyss of the waterfall.

You searched for her for a long time but could not find her for the entire day. The next morning, wishing to continue the search, you see that Kokomi has returned. Except she now looks like... a slime?
