The Jimen Jimen no Mi (Terrain Terrain Fruit) is a Paramecia-type Devil Fruit which allows the consumer to create a square room. Within said room, the user can create any terrain he chooses. Thus making the consumer an Jimen Ningen (Terrain Human). It was eaten by BLANK.

Advantages
Much like the, the consumer creates a room. However unlike its sister fruit, the Jimen Jimen no Mi Within the room the user has full control over the terrain. The user is immune to their own fruit making this fruit dangerous to go against.

Disadvantages
