Oni Oni no Mi, Model: Rakshasa

The Oni Oni no Mi, Model:  Rakshasa ( 鬼鬼のいない、モデル： 羅刹 ) is a Mythical Zoan type of Devil Fruit which allows the user to transform into a hybrid or full version and gain the powers of a Rakshasa. Oni for “Demon", in both Viz Manga, and the FUNimation dub, it is called the Demon-Demon Fruit, Model: Rakshasa  and it was ate by Reiniku.

Strengths and Weakness
The main strength of this fruit is very powerful, according the legends about the Rakshasa “Are depicted as mean, fierce looking, ugly, usually black as soot, with two fangs protruding out of the mouth with nails like claws, growling like a beast. They are depicted as cannibals with an insatiable hunger, who can smell the scent of animal, men or flesh”. The user can have an increase of strength, speed and other attributes. Some of the powers they gain are, having their fingernails being venomous they are said to be power illusionists, and magicians. However these comes with along of set backs as well, the main and odd weakness is that a Rakshasa can’t enter into a home or such without being invited in.

So the user can come with set backs with it, such as the user couldn’t go after someone if they enter into a building or ship. They wouldn’t be able to case after them, this was shown when Reiniku went after a group of Marines who went into an end building. It was like that Reiniku hit a break wall, the user has a much high chance of getting hurt if they come into contact with seastone. It mostly just cancels out powers; it burns the user of this fruit. Other than that the user will suffer for the standard weakness of the devil fruit.
