Two-Dimensional Integration of the World

An imaginary world. There is the Shinigami's Zanpakutō, Kidō, Shunpo, and Hakuda. There are Pirate Haki, Devil Fruit, and the Sixth Form of the Navy. There are Hokage's ninjutsu, blood wheel eye, and blood stain barrier. There are also heroes from Runeterra. There are also bald heads, captains, Uncle A,... It's still difficult to blend in. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
