Doshi Doshi no Mi

Appearance
The fruit looks like a teal tomato with spirals on it and spirally leaves.

Powers
The consumer of this fruit is able to become phase-able for those who consider him an ally, friend, family, and so on. Having no change towards who regard him as an enemy or neutral, making him a friendly fire human.

Usage
The mechanics of this fruit is incredibly complicated to play with, as it depends not on the user but the people around the user to toggle on and off the phase-ability of the user.

The user will not become phase-able to everyone the moment a single ally is near him, instead the ally will be the only one capable of phasing through him, enemies will not be able to phase through in any way, trying to do so when anyone is is phasing will not result in anything other then making a wall that the user cannot phase through, should someone phase into the user and then both be encircled, the person will be trapped inside, but not suffer from shortage of oxygen, food or water for as long as the user himself as access to these.

Trivia
