Fujutsu Sentō

Fujutsu Sentō (巫術戦闘, "Fujutsu Battle") is a fan-fiction series written by Mako. The series is a reversion of the Shaman King story with several influences from series such as Shaman King, Blue Exorcist, Jujutsu Kaisen, Yu Yu Hakusho, Inuyasha, Nioh, and Bleach.

Plot
The story is set in a world where a parallel universe called the "Hidden World" exits simultaneously alongside the Human World. This world is beyond normal human perception and serves as a perfect haven for mischievous spirits to haunt the living.

In order to defend the living world from the threat of phantom spirits, Shamans communicate with allied ghosts and work together to protect the balance between realms.
