Suddenly, you're teleported to a pitch black void. You wander around in hopes of getting out. On your journey, you come across Black Imposter and Chara, and they're having an intense fight to the death. You take a few steps back in fear, but before you can escape, they both notice you.

Chara: Huh, it looks like I missed another one.

Black imposter: I guess we can stop our fight to kill this person.
