This story is about a girl named Y/n L/n. She barely managed to graduate highschool because she was one point away from failing. One day she decides to be a test subject to earn a little money on the side. She winds up in the company of monsters. She happens to meet a certain skeleton and her story goes from there. Disclaimer: I do not own Undertale. Undertale belongs to Toby Fox.

'Filled with power the Queen will rise but loving monsters led to her demise. (Y/n), Queen of Darkness' Frisk stared at the plaque and took a look at the tapestry. A girl with spade cheek marks, around her 20s held a parasol surronded by roses. She was accompanied by a monster who Frisk couldn't recognize but seemed oddly familiar. The two bore matching outfits, the girl a short sleeved purple dress with a white undershirt, a cresent moon decorating it. She wore long purple gloves as well. It seemed edwardian. The other wore a dark purple coat and pants. A white sweater underneath. Maybe they were a couple or something. Frisk shrugged at the thought and motioned for everyone to follow them further into the castle, missing Asgore's, Toriel's and Sans' long stares at the tapestry. "Is that....really them?"

You are about 15, Gaster is 17. In this Gaster is an older brother to Sans and Paps. Asriel is about 6 along with Frisk and Chara, who show up later. You and Sans are best friends, but Gaster is amazing! At age 17 he is the royal scientist and you hope you can help him out.
