After traveling through Naruto, he came to Tokio and became a Kamen Rider Ninja. That's it! !

In a magical world, there are many unsolved mysteries. This book should be about a world of high martial arts. Humans here don't have mindless trolls or overly pretentious plots. Humans don't have intrigues, but they are very greedy. The only enemies are monsters and weird things. (This is the world I want.) Newbies are not good at writing, so try to avoid small mistakes.

Time travel! Time travel! Time travel! The strongest! The strongest! The strongest! Say important things three times!
