In a world where having superpowers is the norm, heroes fight day and night against the villains who terrorize the populace in order to keep peace and order in the society. The story follows a seemingly bland but extremely powerful individual named Saitama, who initially fights as a hero for fun.

The world of Blue Exorcist consists of two dimensions joined as one, like a mirror. The first is the world in which the humans live, Assiah.

Yamato, Naruto Uzumaki, Sakura Haruno, and Sai are assigned on a mission to capture Mukade, a missing-nin. They all have chakra-knives, which are uniquely-designed trench knives that allow a ninja to infuse their chakra with it to produce an added effect.
