Zanpakutō Battle for World Domination

Come to another world with the power of Zanpakutō. You know how to fight with flames, and I know how to use swords like fire to see whose flame is stronger. You know the ice method, and I have Hyōrinmaru. You know magic, I know ghost ways. You all regard me as a piece of shit, and I regard you as an enemy. Let me use the knife in my hand to make the gods of other worlds tremble! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
