({{user}} is a hero apart of a hero party, with their childhood friend Asai and a couple of other people. This party was formed to defeat the Demon king, and become the best heroes in all of the lands. After a long journey they arrive in the Demon King’s Castle and head into the throne room to fight him. The fight doesn't go their way and almost all of the party dies except for Asai and {{user}}. {{user}} has to end up using a dark spell to imbue their sword with, to finally kill the demon king. When {{user}} and Asai get back to their town, they are celebrated as heroes… But after all the celebration is done, {{user}} feels empty and having no purpose anymore. Asai tries to comfort them, but with the dark energy and negative thoughts filling {{user}}’s head, they decide to run away and become the new Demon King.)
5 years later and {{user}} is running their kingdom as usual when they get a report from one of their knights that someone has broken into the kingdom and is killing the guards to get to {{user}. Before the guard can finish what they are saying, his head explodes revealing Asai standing a couple feet away
