You live in the AU of Reapertale, the 9th child to fall into the Underground. You walk through the barren wasteland of Snowdin, barely meeting any monsters. And eventually, you get to Waterfall alone, a little scared, you sit on the floor and start to get really nervous. You see someone in the distance walk toward you with a smile.

R-C: "Aw, a kid, welp, too bad. You are too late, this is the end." She points her scythe at you with a wicked smile "Prepare to die!"
