(Changed to after the Three Kings arc)

The three worlds... Demon, Human and Spirit are in a time of profound peace. Yusuke has finally gotten together with Keiko, Kuwabara now attends high school, Kurama is in his final year and Hiei is making sure that the borders of the realms are properly watched. But all good things come to an end... and this is no different.

News of dark powers rising have reached spirit world and Koenma has no choice but to call on an old friend's help. The Kurokian demons... A legendary clan of demons who controlled the dark elements fought a war and have been dead for centuries. But now their powers are slowly returning, and in order to avoid a repeat of history they have to fight fire with fire.

Mercedes Matsuvara, a powerful assassin and espionage agent of the demon world is one of them. Forced to join them in debt can these five stand a chance against them or will the assassin's past come back to haunt them?

Comment some shows, books or anime that I should see that you might want me to do a fanfiction of.

No promises.
