Uni is a member of the Heart Pirates.[1] His name was revealed in SBS Volume 83.[2]


Uni with eyes.

Uni is a tall man with puffy light hair (dark brown in the anime). It is unclear whether his eyes show to have irises or pupils, as he has appeared both ways. He wears a gray bandana with vertical black stripes on his face, which covers his entire face and goes all the way down to his upper chest. Like most members of the Heart Pirates, he wears a white boiler suit with the Heart Pirates' Jolly Roger on the left breast.[1]


Along with Ikkaku and Clione, Uni was against the idea of allying with the Straw Hat Pirates, thinking of their assistance as worthless.[2]

Abilities and Powers

Uni wields a staff, though he has not been seen using it.[1]



A month before Trafalgar Law formed an alliance with the Straw Hat Pirates, Uni and the other Heart Pirates went to Zou[3] and were left under the watch of Nekomamushi.[4] Uni, Ikkaku, and Clione were against forming the alliance, but they were outvoted.[2]

When the Beasts Pirates, led by Jack, invaded Zou in search for Raizo, the Heart Pirates fought alongside the Mink Tribe.[4]

Four Emperors Saga

Zou Arc

After Law arrived at Zou around a month and a week later, the Heart Pirates happily reunited with their captain when he came into the Whale Forest.[5]

That night, the Heart Pirates briefly met and greet Monkey D. Luffy before Law went to have a private conversation with the Straw Hats. The Guardians later threw a party for the Straw Hats that lasted throughout the night, which the Heart Pirates joined in.[1]

The next day, the Heart Pirates, some of the Straw Hats, Kin'emon, Kanjuro, and Raizo prepared to depart Zou for Wano Country on the Polar Tang.[6]

Wano Country Arc

The Heart Pirates later infiltrated Wano Country. After Law was captured to free Bepo, Shachi, and Penguin, the Heart Pirates gathered in Ebisu Town and discussed about their captain's situation.[7]

The crew later reunited with their captain and they entered the battle with the Beasts Pirates on the day of the Fire Festival. After rescuing Kin'emon's group, the crew was shocked to hear that Kaido formed an alliance with Big Mom.[8]

After the guards at the torii gates were defeated by the Straw Hats, the Heart Pirates and the Scabbards (except Kin'emon and Denjiro) traversed to the back of Onigashima in the Polar Tang.[9] When the submarine got close enough, it rose to the surface and Law teleported himself, Bepo, Shachi, Penguin, and the Scabbards with them to Onigashima's back entrance. Once they left, the rest of the crew submerged back underwater.[10]
