Y/N POV

I cant just stand here. He'll die out there. I stood and ran out the door in hot pursuit.

Gaster Sans POV

I ran as fast as my legs could take me. The humans and monsters were fighting at the bottom of Mt. Ebbot. My eye glowed fiercely as I summoned two Gaster Blasters. They fired at the humans. Driving their ranks down slowly. I felt a force and was knocked to the ground. Dazed i looked up to see a man. "Any last words skeleton?" this man sounded familiar. Wait. He was the man i saw yelling for y/n! It's her father. "You..." I spat venom in my voice. "You hurt my y/n..." a burning twisted feeling was felt coursing through my bones. I knew this feeling all too well. Hatred. "I'll kill you.." I growled out. I used my magic to turn his soul blue. I flung him off and into the ground. I smiled in satisfaction. I continued this till I was sure he was dead. I spat on his corpse and turned towards the battle. I then heard a scream. "Y/N!!" I called out and ran towards the scream. Please for the love of asgore. Let her be ok. Please.
