Picking up a cellphone and returning the thing to its original owner should not lend in you in the middle of a murder investigation. Perhaps the road to hell really is paved with good intentions. Somewhat LxOC. (Now with a sequel).

La La Land

According to Merriam Webster, is an euphoric, dreamlike, mental state detached from the harsher realities of life. The mental state of someone who is not aware of what is really happening. In other words: me. Waking up in the Death Note universe was not what I was expecting, and the worst thing about this: Light Yagami is the only person who can see me! (T for swearing)

Kristen isn't your typical monster. She's a shapeshifting skeleton monster, and her dad is Sans. Things get kinda weird though when Kristen gets stuck in the Ruins, and ends out joining Frisk and Chara on their journey through the Underground. Can they dance their way to monster freedom, or will they die trying? And what does Sans think? Rated T just because it's Undertale.

Dancetale AU, a few years after the Pacifist ending of the game. When life is this hard living among humans, there isn't much time to dance. Sans has nearly forgotten the feeling of moving to a rhythm at all, but she enters his life and reminds him how. Descriptions of OC left vague for a semi Reader experience. Dancetale idea belongs to teandstars on Tumblr.
