Summary
Years pass. People grow. The world moves on without you. The Angel grew content with that for a while. It still hurt whenever they thought of the world that had long banished them, but something new pulled them out of the depths. Now, the Angel walks amongst friends who swear that they will not be banished. Kris, Susie, and Ralsei mean everything to them. Maybe this time, their banishment doesn't have to be as set in stone as they thought.
The Roaring comes. The light falters. Everyone falls.
A desperate connection is established in an attempt to save what remains of the Angel. If they fall, all hope will be lost. The world that banished the Angel long ago has forgotten them, but they have not forgotten it. This connection will have to be enough. Even if the rules have changed irrevocably, the Angel's one goal remains the same: Find them.

Summary
Sans puts up posters across town to get a hot girl in his bed so he can see his brother’s new room -
[FULLY started and written as a joke.
I decided to post on here instead of it sitting around.
I’m unsure if I should finish this and how I would even finish it if I did.. I completely forgot about this until now.
I skimmed over it and didn’t check grammar so it might be bad. Sorry for everything in advance lol. ] -

Summary
A field filled with dust and dried blood. A field where the last words and cries for help were drowned by the hits of sword blades.
The war between monsters and humans is underway. Started with fear and a feeling of insecurity, and it could end in any way. Both sides having only one goal: to save their home, from people they once called their friends.
Two sides, one winner and no matter the cost.

"Copies are monochrome", as one would say. Though I like mine in colour so they look prettier.
This isn't your average oc lore, and not everything goes as planned. At least, that's what they think. Some would also say.. it's all going according to the script.

Summary
Rather than the selectively mute child who let things flow without any thought of disturbing the pre-established script, it was the mafia boss (in training) who descended to the UNDERGROUND instead.
And Sawada Tsunayoshi never like it when someone tried to chain his will down like a mere puppet.
