Name: Potaru Potaru no Mii.
Translation: Portal Portal Fruit.
Fruit Appearance: The Fruit is an odd shape of a fruit as it doesn't appear much of any kind of fruit, it's a flat spiral fruit.
Type: Paramecia.
Effects: This Fruit grants the user to create portals between two points in space, the form of the portal appears to be a wispy smoke which is spiraled into a point of space.
Connecting portals is another matter as while these portals have utility uses, it's primary use is transportation between two points, the weakness to portal generation is that the user needs a clear concrete idea to where they are going for two portals to be connected.
this can range to the easiest aspect of sight however this goes only so far as with sight, the user can generate as many smoky portals as they like which can be used to redirect incoming attacks of both physical or energy back at any point they see within range.
Or the more difficult aspect of out of sight which the user will require a combination of an image as well as coordinates though completing both of these will allow the user to connect a portal to theoretically any point in the world.
