The Uo Uo no Mi, Model: Seiryu is a Mythical Zoan-type Devil Fruit eaten by Kozuki Momonosuke. This fruit is an artificial Devil Fruit created by Dr. Vegapunk, considered a failure due only to its pink coloration.

The fruit allows Momonosuke to transform into an eastern dragon, granting abilities such as flight via flame clouds, immense size, and elemental breath attacks. Though inexperienced at first, Momonosuke gradually learns to use the fruit during the Wano Country Arc.

This fruit is a direct counterpart to Kaido’s Mythical Zoan.
