After the events of "Unitale: The Darkened rooms" You find Chara and explore numerous universes with her while having fun and being a cute couple.

A undertale au where you, all your classmates and a new girl in a green jacket wake up in a dark room, fighting for your lives doing fatal challenges for the amusement of some mysterious thing...

i will refer chara as a Female. but I will write a male version of this and the reader/you are He

A story of a kid who fell down and a person who had made a promise to protect the kid... 'Will they be different from the others?.. Who had chosen a Genocidal path or... Will they be a nice kid?' The person thought. 'Are they really what they thought they are?' The kid thought. But... Slowly... Everything changed after the kid had met that person... You fell for them...

Any Gender yay! Chara will be any gender and including you so I hope you enjoy bye~

It's been over 2000 million resets, and Chara was ready to give up on the world. But what happens when instead of Frisk, you fall down? Can you save Chara from depression with the power of true love?

(So... Let's try this again, Shall we?) "Frisk? Why are we are we here? No one ever comes back from this place..." "W-Wha? W-WAIT N-NO FRISK DON'T-"

This is my first story I've posted, so no hate, please. Also, even though the title says storyshift... It's not going to seem like that for the first part of the story. In the story, you are 16 btw.
