World view: A fusion of the Taisho era background of "Demon Slayer" and the ninjutsu system of "Naruto". Ghosts are still monsters that hide at night and feed on humans. Sunlight is their fatal weakness, and Demon Slayer Muzan is the mastermind behind the scenes. The protagonist's Hokage system can provide chakra refining, ninjutsu, blood succession limit and other abilities. Chakra and the breathing method of the Demon Slayers can be integrated with each other to derive a stronger fighting method. Human society is ignorant of ghosts and ninjutsu. The Demon Slayer Corps is a ghost-slaying organization hidden in the dark.
