1 Work in Blue Soul Human & Mettaton (Undertale)
Once upon a time, a human fell into the Underground. Chara poisoned herself and her brother Asriel used her soul to cross the barrier. But, in the end, their plan failed and it took the lives of six more humans for the monsters to finally go free.
...But what if Chara survived, and the other humans fell to find a world that welcomed them? Perhaps freedom without bloodshed is a possibility after all.
