Karasu (Non-Canon)

This sizable bird has the build of a gull, its plumage mostly white save for blackened wingtips and tail. A hooked yellow beak ends in a black point, its eyes are yellow, and a skull-shaped mark with orange sockets sits across its chest. An orange collar is fastened around it.

The creature seems to have been drilled to follow whatever the Lytton Food Thieves tell it. Outside of that obedience, it shows no real character of its own.

As the Straw Hat Pirates passed by Cream Mist, the bird dove in and made off with their Eternal Pose set for Arabasta, delivering it to the crew waiting on Granu Island, who handed it to Cello. After the Straw Hats gathered every Life Gem and brought down Lytton, the bird turned up beside Cal in Cello's mansion. Its presence tipped the crew off that the Food Thieves were behind the theft, prompting them to demand Cal reveal where the pose had gone. What became of the bird once Cal and Lytton were taken into custody by Smoker is never explained.
