After the monsters are set free, they aren't too keen on befriending humanity. They won't show themselves yet. They will get revenge on the war the humans had waged years ago. Now they attack in secret, getting patrols and assassins prepared at nightfall. One of the pairs of assassins is Gaster!Sans and his brother. When they find a girl who is pretty, kind, and peaceful, maybe they will have a change of heart after all. (Gaster!Sans X Reader)

She loved to sing and dance and rhyme. But her happiness was running out of time. She screamed and clawed to anyone at all, Because blood and skin couldn't break her fall. Tears and sobs and screams ran out, And still nobody heard her shout. Humans, monsters, but nobody came. And to everyone else they did the same. She was lucky he was being kind that day, So he didn't take her life today. Smiling and happy, her journey began, To free all monsters was her plan. She wasn't perfect, But it was worth it. She didn't want to be best. But despite everything, she never reset. (Horrortale!Sans X Reader)
