Na Na no Mi

A Paramecia Devil Fruit that allows the user to erase a person's name, ultimately making the victim forgotten from the world, but still living (if they were alive when the powers were activated). When the user of the fruit dies, or do it willingly, all the people that have lost their name from this fruit's power return to their original owners, making all the memories people have had of them return as well. Another power of the fruit is that it allows the user to assume one of the names they have erased. It was eaten by Mysteri Season of the Imperial Pirates.
