Welcome to my world! "Before I traveled through time, there were people who thought a certain character was very powerful. They would compare them horizontally, vertically, and even across the world." "For example, can Uzumaki Naruto defeat Monkey D. Luffy, for example, can Superman defeat Captain Marvel, for example..."

Unrestricted fighting has become a small competition. Isn't the real big scene not that the Naruto world officially declares war on the One Piece world?

"Welcome all careerists, welcome to my world!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
