Field trip to the ghost zone with a demon king?!

Blue exorcist and danny phantom crossover

My own sequel for Demons and Ghosts, Hell's king and king of the dead.

This is a story where Rin's identity as Satan's spawn has been told and he didn't go home. Satan actually cared for Rin and gave him the throne after their spar. (Satan loses) He and his brothers are friendly to each other in their own demon way.

Danny's parents didn't know their son's identity as Danny phantom.

Mr. Lancer decided to go to the ghost zone to learn how to protect themselves against the demons and ghosts.

Will Danny get out of this disastrous turn of events without exposing his secret?

Or will Maddie and Jack rip every ghost apart molecule by molecule?

Join Rin, Danny and co. as they travel in the ghost zone, relieve dangerous situation and have lots of fun.
(Blue exorcist and Danny phantom do not belong to me. Neither does the cover.)
