Au where Frisk is a vampire and can only feed off humans, and Chara is the only human in the Underground. Chara survived the sickness from the buttercups and didn't die, meaning Asriel didn't become Flowey. Frisk is the first human down since. Blah blah blah. Summary.

Frisk is part of the underground's mafia. So is Chara, and Asriel. What else... OH WAIT! MATURE BECAUSE SWEARING, ALSO A SIN CHAPTER ON 15. ART IS NOT MINE, BASED OFF MAFIATALE.

Two years after the events of MERCY. If you have yet to read MERCY, read it on my profile! Graduation time. Frisk and Chara's relationship lasted a glorious two years together. Chara is now nineteen and Frisk is now seventeen. Frisk's MERCY had never faded or failed, and Chara thanks their DETERMINATION for keeping them both together for so long.

My first fan-fic about Charisk! I hope you enjoy. ~Little side note- The book cover does not belong to me, but rather hamvitita on DeviantArt. (I added the words with the Cover's app though.)

Frisk has been followed around by Chara since they fell into the underground. After seeing Chara express a want for their body Frisk decides to give them their body back. Of course Chara can only have it under Frisk's watch.
