This is a AU of Ragnartale where Sans and Frisk have a daughter named Esmeralda around 16... Esmeralda has blue eyes and her left eye can glow blue like her father when threatened or angered, she has white hair and has a light blue dress on with a red overcloak that protects her from the weather like her father's blue overcloak. Esmeralda has her right arm skeletal like sans but her left arm is human like Frisk, Esmeralda can summon a light blue sword to her will, bones, her own integrated Gaster Blasters, Teleportation, and Blue Fire which surprises sans and she has been known to integrate her attacks with her fire. Frisk is the Ex-Princess and now Queen of the kingdom of the humans after her father died and her sister Chara ran away and would later marry Asriel after corrupted deals with Gaster to make it happen unfortunately Sans made a deal to keep Frisk away Asriel with Gaster and Gaster erased all of Frisk's memories... After the battle between the Resistance and Asgore's kingdom they learned that Gaster was using them against eachother unfortunately escaped making Sans very protective over his daughter and his wife since he doesn't trust what Gaster will do... Sans has been known to spar with Esmeralda with swords but has to put on armor due to his 1 Hp condition but he still can dodge well in his armor... inside the castle where Sans is sitting with Papyrus and Frisk talking with eachother Frisk: YOU DID WHAT?!?! Her eyes goes wide and she tries to hold back giggling Sans: I-I gave her the Grillbys special ketchup in the mug... and... well... umm i let her have a sip... what a waste of ketchup He chuckles nervously Papyrus: Sans... letting your daughter drink... was not a good idea... He mumbles Frisk: sans... don't let our daughter drink the ketchup again She smiles faintly and Esmeralda teleports in Esmeralda: hey dad, mom... She smiles and sits beside them she tosses Frisk's crown to her Esmeralda: you left this... thought I might grab it for you
