Rakuyo

Rakuyou is the commander of the 7th division of the Whitebeard Pirates. His name was revealed in a SBS of Volume 58.

Appearance
Rakuyou is an average-height man with dark blonde dreadlocks. He has a mustache that consists of two straight points angled diagonally. He wears a typical outfit consisting of a yellow coat with green linings, a vest under an unbuttoned shirt, a standard pirate sash, square-patterned pants, and standard boots. His outfit most notably includes a yellow and purple bandanna bearing Whitebeard's mark. He is often seen wielding a unique spiked ball and chain that has a face at the end.

Abilities and Powers
As the commander of the 7th division of Whitebeard's crew, Rakuyou has authority over the lower-ranking subordinates. Like all Whitebeard commanders, he is very strong. Also, he appeared unharmed after his confrontation with Admiral Kizaru, despite the latter possessing destructive light-based powers, which suggests he must be particularly powerful (in strength and/or speed- wise).

Weapons
Rakuyou possesses a chain with a large spiked ball attached to it, which appears to have a canine-like face on it. By hurling the spiked ball towards an opponent, he is somehow able to make it chomp down on them. It is unknown if this weapon has "eaten" a Devil Fruit or has some sort of mechanical device that allows it to move.

Marineford Arc
When it was revealed that Ace was going to be publicly executed in Marineford, Rakuyou joined the rest of Whitebeard's fleet and their allies to rescue him. Arriving in the Marine headquarters, they fought to save their captured comrade alongside some late additions to the war. He personally fought Admiral Kizaru, making his spiked ball "bite" through him.

He cried as Ace pronounced his last words, calling his name, and also was seen crying, begging his captain to come with them, when Whitebeard announced his decision to sacrifice himself in order to save his "sons" and also when he was killed by the Blackbeard Pirates. He then faced Akainu with the other Whitebeard Pirates and Crocodile, in order to protect Luffy. He was seen with the other Whitebeard Pirates, mourning the results of the war. Upon the arrival of Shanks and Sengoku calling the war to a close, he and the rest of Whitebeard's crew left.

Post-War Arc
He, along with the rest of the crew attended the funeral of Whitebeard and Ace at an undisclosed location somewhere in the Grand Line.

Trivia

 * Rakuyou's weapon vaguely resembles the Chain Chomp enemy from the Super Mario franchise in design.

Anime and Manga Difference
In the manga, when Rakuyou hurled his chainball at Kizaru the ball chomped through him, in the anime it was just shot through his body.

His chainball also appears to be bigger in the manga.
