State state fruit

Bestows the user with immortality and regeneration that allows them to remain in that state when they get the fruit permanently. If the user's body is changed thanks to losing limbs or dying, their body will automatically return to that previous state. The user can eve bestow others with this immortality. The weakness of this fruit is that the user will never physically change, age or get stronger because because their body will always return to that state. Also if the user or bestowed users lose their ability due to seastone or having it taken away, they will experience the damage that they took while having the ability such as aging, dying, losing limbs etc.

This is a double edged fruit. What do you think? This is my idea of Imu's devil fruit.
