Summary
❤️For the past six years, you have been living as the only human in the Underground. Over those six years, you have made a better life for yourself than you ever could've had on the surface. You work as an apprentice at the Royal Lab, play piano gigs on the side, and have the greatest family you could ask for. Everything is perfect. That is, until a second human falls.
💛One month ago, your best friend disappeared when visiting Mt. Ebott to research the magic used to seal monsters away. After the search parties stopped and her family gave up hope, you decided to climb the mountain to find her yourself. One vine-snagged boot later, you find yourself in the Underground forced to make peace with your new life.

Summary
Dust, nothing but dust and sky filled his vision. He stumbled haphazardly onto his feet, drawing in belabored breaths, taking in the scene around him all the while. They were all laid bare in the empty wasteland, though discerning who “they” were was an impossibility.
-In other words-
What if Chujin lived and Ceroba Died instead?

It was supposed to be just another repetitive run like always, but it seems things on this timeline were gonna get a bit... weird.
A talking triangle and a talking flower? Who was Clover supposed to trust?!

Summary
“Stop messing around. We’re supposed to be keeping watch.” Cross huffed, turning to face XChara fully.
XChara glared at the snow when Cross said that. He reached down and scooped up some snow into his hand.
XChara ignored Cross’s attempts to get him to lock in. “Whatever” Cross rolled his eye lights and turned back to face the crowd of people, but was hit by something cold and hard on the side of his skull.
“BAHAHHAHAHA!” XChara was rolling on the ground clutching his stomach from laughing as he watched the snow slide down Cross’s cheek.
