Kaiku Kaiku no Mi

Introduction
The Kaiku Kaiku no Mi is a paramecia Devil fruit that allows the user to force the target to undergo evolution, adapting it to overcome a certain limitation.

Usage
Activating the power of the Kaiku Kaiku no Mi requires the user first to touch the object being targeted. Activating the power will enclose the target in an "evolution bubble" that resembles a glowing red sphere around it. This sphere can be used to simulate certain limitations or hinderences that may affect the object's devellopment. They can then attempt to force a change in the object which will adapt it to better overcome the imposed limits within the sphere. The user can not actively control what change this may result in normally, and instead must carefully consider how each limitation may affect it's devellopment. Notably, even non-living things, which are not normally capable of evolution, can be subject to this fruit's power. Another use of this fruit, which can bypass the random evolution effect, is to "splice" the effects of this fruit's evolution cycles between similar objects, allowing them to gain the same changes. This requires that the object recieving the spliced evolution patern is sufficiently similar to the unevolved state of the donor, and if used otherwise will most likely result in the change being rejected.

Weaknesses
Apart from the standard weakness of all devil fruit, the Kaiku Kaiku no Mi is one of the hardest devil fruit to make effective use of, due to the limitations of its basic techniques. The evolution bubble can only simulate limiting effects, and not actually impose them, and thus despite its appearance is entirely useless for offensive purposes or for hindering a target. A much larger weakness is in that the evolution process must be gradual; If too many limitations are imposed at once, the target may not evolve at all, due to the required changes being simply too drastic. The user must instead gradually adapt the object through multiple evolution cycles, each with different requirements. Possibly the most significant weakness, though, is that careful consideration of how the object is most likely to evolve is the only way to have any degree of control over the changes, and produce a specific desired result
