Naoki, a Senju orphan after World War II.
As a young child, he should have lived his own leisurely life and become a qualified ninja in the future.
But who knew that the Sandaime and Captain Nabei would eventually reach out to helpless orphans like him due to the lack of willing experimental subjects.

Just when he fell into despair, the template system found him.
Take a trip here. . . .
OK, but not to my taste
