Promotion from Navy Headquarters

The Dark Fruit can only invalidate Devil Fruit abilities, and Dark Water can absorb slashes at most. It cannot be said that a person is touched by Dark Water and cannot even use sword slashes. Please check the information carefully before writing a book.

The sister is very annoying, and there is a familiar smell. Could it be a harem story where a beautiful woman secretly and madly favors the protagonist, and then accepts them all in the end?

As long as you don't defect, too many people defect in this way after joining the navy!

Why do you want to find a sister →_→? Looking for a dragster?
