Ikkaku

Ikkaku is a member of the Heart Pirates, being the only female in the group. Her name was revealed in Volume 83's SBS.

Appearance
Ikkaku is a woman of average size with long and bushy dark hair, which she puts over her shoulder. Like all the other members of the Heart Pirates, she wears a boiler suit with the crew's Jolly Roger imprinted on the left breast.

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

Past
A month before Trafalgar Law formed an alliance with the Straw Hat Pirates, Ikkaku and the other Heart Pirates were left on Zou under the watch of Nekomamushi. Ikkaku, Uni, and Clione were against forming the alliance, but were outvoted.

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

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.

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.

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.

Trivia

 * Ikkaku means "narwhal" in Japanese, corresponding to the cold climate animal naming theme of the Heart Pirates.
