Runa Runa no Mi

The Runa Runa no Mi (ルナルナの実, Lunar-Lunar Fruit) is a Logia-Type Devil Fruit that allows the user to create, manipulate and transform into moonlight. Making the user a Lunar-Human (月面人間).

It was previously eaten by a mysterious pirate who utilized its power for his own personal gain. After he died, the fruit went back into circulation and has yet to be found again.

It's considered to be an inferior version of the Pika Pika no Mi, as it does not allow the user to move at light speed.

History
The fruit has been utilized in the past before by a mysterious pirate who's never revealed his name to the public. He considered himself a One-Man-Army, after eating the Runa Runa no Mi, and thus never had his own crew. With the power of the Devil Fruit, he had embarked on a selfish quest for riches.

Raiding town after town and never getting caught, due to the powers of a Logia rendering him intangible. He rampaged through Paradise, until one day he was caught off guard by a fleet belonging to the Marines.

Being shot by a Seastone Bullet, he was rendered powerless, and was easily overpowered by the Marines. On the same day, he was executed for his crimes.

The moonlight that the fruit can create is identical to that of an actual full moon. And because of that, it has been rumored that the fruit can be used to forcefully transform a member of the Mink Tribe into their Sulong form.

However, that idea is looked down upon the members of the Mink Tribe, due to it not being a natural transformation when the actual moon isn't involved.

But that didn't mean that there wouldn't be anyone after the fruit for this very purpose. It has not been found ever since the original user had died. Most have given up on finding it.
