10 years later.
"Another one, Grillby." Sans Gaster said, setting down his empty bottle for a new filling of Grillby's special ketchup.
"You sure? You've had more than enough tonight." Grillby asked.
"Come on, Grillbz. You know I'm not a lightweight." Sans grinned as he took another bottle of ketchup by reaching over the bar. He and Grillby had been friends since before Grillby opened the bar so it wasn't something that he'd get yelled at for.
Grillby sighed before nodding and attending to other customers while Sans popped open his new bottle of ketchup. This bar was one he had been going to for years and everyone knew him whenever he walking in the door. He looked over at the clock on the wall to see it was nearly midnight and sighed. Papyrus wouldn't be happy with him getting home so late but he had the day off tomorrow so he had decided to go visit his friends bar to relax and get some drinks.
Of course, as soon as he stood up, another man over at one of the tables stood up, grabbing the other guy who had been sitting at his table by the collar of his shirt and punched him hard enough to cause him to crash into another table, causing the girl and man who had been sitting at that table to jump up and cuss him out. This lead to a fight between all three guys. Sans sighed again before glancing over at Grillby who was giving him a 'Well? Do something.' look.
Sans nodded and turned to the fight and was about to use his magic to stop the humans only for 2 dog monsters and a fish monster to walk in and each knock one of the humans out. The fish monster had blue skin and bright red hair that she tied back into a high ponytail with bangs hanging down one side of her face. Her large, sharp teeth stuck out of mouth, not that she was trying too hard to hide them. She was just a little shorter than Papyrus and wore a conventional gray men's suit that was just tight enough to show how thick and strong her body was. There were seven tubes coming out of the back of the tank and each one seemed to be injected into different areas of the fish's body outside her suit. Two tubes were injected into her elbows, two were stuck in the back of her knees, one was directly into her throat, one was on the back of her neck and the final one was in her mouth. Her one black eye looked down at the unconsious humans.
The fish monster looked around as the other customers looked at the three of them in shock.
"Dogamy, Dogressa, dispose of this trash before the boss' show up." the fish monster ordered.
Both of the dog monsters were large, almost twice the size of the fish monster but something told Sans that it was mostly because of their white fur. They both wore matching gray suits that were a shade or two lighter than the fish monster's suit. The two dog monsters nodded and grabbed the humans by their arms and clothes before dragging them out. Silence spread throughout the bar and the fish monster glared at anyone who would meet her eye.
"Either get out or sit down!" she ordered, which triggered a all of the customers of both monster and human races either shrugging and sitting back down or rushing out of the bar.
The fish monster, Sans recognized her as Undyne, the head guard of a mafia family in town.
'Must be a night off for her.' Sans thought as he took another drink of his ketchup.
"What are you lookin' at, skeleton?" Undyne growled, looking at Sans who had been watching her.
"Jus' wondering why a mafia head guard would visit a bar this late at night." Sans explained. "Don't worry. I won't cause anything. I was just about to take care of that fight before you showed up and did it for me."
Undyne glared the the skeleton before they both turned back to the door where Dogamy and Dogressa had walked back in, being followed by two human women. One had short, messily cut brown hair that was pulled back in a ponytail and walked with a sense of superiority with her head held high as she walked. She wore a black suit that was neat and expensive looking and had a permanent sneer on her face as she looked over everyone with the same, if not worse, glare than Undyne with her bright red eyes. The other woman had longer brown hair that looked more naturally cut and hung around her shoulders and was wearing a white sweater dress that complimented her body but looked comfortable and a black suit jacket hung off her shoulders that looked like it was the coat to the other woman's suit. She followed behind the woman in the suit as she looked around with her lighter red eyes and a softer look than the other woman.
Sans couldn't stop staring at her.
