Daiya Daiya no Mi

The Kuri Kuri no Mi (くりくりの実; Literally meaning "Crystal-Crystal Fruit") is a Logia-type Devil Fruit that turns the user's body into crystal, making its user a Crystal Human (結晶人間 Kesshō Ningen). While Shion refuses to explain how he ate this particular fruit, he does mention that he ate the fruit before forming the Dream Pirates.

Appearance
The Kuri Kuri no Mi takes the form of a large peach, except clay-like in texture and gray, with luminescent pink lines running through it. Due to this, the fruit is known to be able to glow in the dark. When it is first bitten into, the fruit's light dimishes, then goes dark, and finally, the fruit is entirely gray.
