It was just an average day in the underground.

You are a skeleton monster, and the brother of Sans and Papyrus.

Today you were just in your room reading a book, since your brothers were out scouting for humans.

Out of nowhere, suddenly, a red glitchy portal opened and a girl stepped out.

She locked eyes with you as you stared at her in shock.

”Greetings…I am Player.”

…Who the heck is this girl and why did she just appear in your room?!
