Jin's story as Killer Sans

This is a story about a guy who gets reincarnated into the Undertale multiverse as a Killer Sans. You might be wondering how he died and ended up in such a place. Well, it all started in an ordinary night. He was peacefully asleep, unaware that he had left the stove on. In a tragic accident, the house caught on fire. He never realized what happened—just perished along with his burning home. Now he's in a massive, chaotic multiverse filled with alternate versions of familiar faces. What will he do next? Only time will tell. Oh, and fair warning: the chapters are going to be somewhat short cuz the writing isss super bad lmaoaiaj.
