Demon slayer x PJO

Yes, another PJO crossover, I find that there aren't enough. Anyways, you, Percy, Anabeth, Grover, and Nico are sent back in time on a mission. Ya'lls mission is to find and kill all demons so you will be working with the demon slayers. There are all demon slayers (yes, including the ones that died in the show). You guys are teleported to right before final selection on the mountain.
