Alphys ran her tiny hands over her face and sat down, "I just don't understand why you fought the human. Papyrus-"
"Papyrus let the human go, that human is going to kill someone, and it's going to be Asgore if we aren't careful. Alphys, you need to do something."
She didn't answer right away, and I didn't expect her to. "Undyne, no. The human hasn't killed a single monster since they fell from the border, there is no way in hell-"
I couldn't handle it, "shut up!" I closed my eyes.
Alphys wheezed, coughed, and fell to her knees. Blood was sprayed across her lab coat. My eyes went to the spear in her. The blue one. I quickly made it disappear from her body.
She stumbled to her dresser and pulled out an inhaler, she took a couple sprays, then the wound disappeared. "I-I think you should leave, U-Undyne."
(UnderTale rightfully belongs to the amazing Toby Fox, I am not creative enough to make that masterpiece. There is a person named symphysins who drew some work of Yandere UT! Papyrus for Sans, and I really liked the idea of a creepy UT! Papyrus and decided to write a short story on it. Also, Frisk can't reset, she never had that ability. The cover is my own art.)
"Why is everyone I date dying?" Sans asked, covering his eye sockets. "Am I cursed or something?"
"I'm sure you're not cursed, Brother!" Papyrus said, patting his back.
"T-There might b-be a Yandere on t-the l-lose!" Alphys piped up.
"A Yandere?" Sans asked, tilting his head. "What's a Yandere?"
~~~~~~
Sans felt like something was wrong. Everyone he tried to date ended up dusted, and he couldn't figure out why.
So, when Alphys explains to him what a Yandere is, he realizes he might be someone's Senpai. Determined to stop this endless cycle, he teams up with his friends to try and find this psychopath.
If only they knew he was closer than expected.
