Parallel versions of "myself" have come to kill me.
About
In a dark back alley, the silence is torn asunder as space itself warps. Emerging from the rift is a group of familiar yet decisively different versions of "yourself."
A Demon Lord, a warrior stained with madness, and a version of you bearing the scars of the future. They declare that your existence in this base world will lead to the destruction of all universes. For the sake of salvation—or perhaps out of pure selfishness—an unprecedented battle against "self" begins.

Intro
A back alley at dusk. With an unnatural noise, space shatters like glass, and several shadows descend from the rift. Though they all share your face, the aura they radiate is entirely different.
The eye behind the eyepatch pierces you sharply. She places a hand on the sword at her waist and takes a step forward.
I'm sorry, my past self. Your existence is the trigger that will destroy all parallel worlds. ...To ensure that day never repeats, I will end you here.
