Akibi is a member of the Pumpkin Pirates. Together with his friends he was in the grave of the galleys.
Akibi has black hair and at the time owned a green shirt that he wore open and tied at the ends. Underneath he had on a blue t-shirt with white dots and light brown pants.
When they were children, Henzo, Rapa Nui, Pukau, Isoka, Rongo and Akibi often met at a big rock in the sea, went swimming and talked together around the campfire in the evening. One afternoon, when they met together once again, they saw from afar how the town was on fire. Worried for their families, they ran to it and met the captain of the attacking pirate gang, Wetton, of all people in the town, who was having fun chasing the children.
Rapa Nui led them to the harbor, where his plan was to grab a ship and run away. But the pirates had destroyed all the ships, so the children climbed aboard Wetton’s pirate ship. The latter jumped in after them, and tried to grab the children. He hurled his axe and managed to destroy the steering wheel. Unfortunately, the ship was heading straight for the Rainbow Nebula, which Ian, who was left alone on the ship, was not at all pleased about.
Wetton still tried to fight the children, though. Henzo unexpectedly threw himself at him and they both fell off the ship before the ship even reached the Rainbow Nebula. Akibi, his friends, and Ian thus sailed into the mist, where they did not age, and Henzo and Wetton swam back to the city.
Under Ian’s command
In the fog, Ian made it clear that they would now have to listen to him if they wanted to survive, as the sea was dangerous and he was an experienced sailor. The children now fetched food and treasure from the other ships at his command, most of which he kept for himself. He treated them badly and even threw Rongo to a sea king so he could fight him, but he was saved by Rapa Nui. Once again, as Ian was feasting, a sea king showed up, attracted by the food. Everyone was terrified, and Ian ordered the ship to be defended. Rapa Nui was outraged that the ship was more important to him than her life. Together they left the ship on a dinghy and the sea king swam after the ship.
Meet the Straw Hat Pirates and Henzo
When a group of pirates appeared in the Rainbow Mist, the Pumpkin Pirates executed the plan for such a case. Ghosts made of sheets were piloted from the mast and arrows were shot from the shipwrecks. Luffy, however, uncovered the hoax and exposed the children. Rapa Nui showed up and threatened to set off a bomb if they didn’t let them go. Henzo recognized his childhood friends, who hadn’t aged a day, and also realized that the bomb was fake, as he had designed it.
The pumpkin pirates were skeptical, whereupon Rapa Nui set off a smoke bomb and they disappeared. In an old naval ship where they had locked Ian in a cell, he and Rongo reported to him that a man had appeared pretending to be the aged Henzo. Ian questioned this, saying that if they would let him out, he would show them the way out of the Rainbow Mist. Rongo and Akibi were inclined to do so, but Isoka prevented them from doing so.
Shortly after, Isoka was informed by Rapa Nui that the pirate ship from earlier was approaching. Rapa Nui spotted Pukau aboard the The Going Merry and thought the Straw Hats had kidnapped him. He therefore jumped onto their ship with his sword drawn, but was disarmed by Zoro. Eventually, everyone except Rapa Nui no longer distrusted the Straw Hats, and they ate together.
Henzo’s Den-den Mushi rang and he wanted Flip to bring his invented device to him in the mist. Usopp settled the dispute between Henzo and Rapa Nui and just as they were about to make up, Luffy’s too much momentum accidentally took Rapa Nui to the edge of the Rainbow Nebula, where they were stuck for the time being. Ian was released by Rongo, allowing him to blackmail the others. He wanted the boat with the rope out from Nami, who had arrived just before. Ian finally escaped the fog that way.
Escape from the fog
As Henzo had feared, Ian’s information caused Wetton to activate the rainbow tower, which was a tube that went into the fog and allowed Wetton to have his troops search for the treasures. Wetton, seeing that he stood no chance against Luffy, used a lever to explode the tower.
The explosion made the fog unstable and they had to get out of it quickly. The air blast from the cannons fired from the wrecked navy ship finally got the Going Merry outside.
Joining the Navy
Rapa Nui, Isoka, Akibi, Pukau and Rongo all woke up on a beach and were picked up by a navy ship. They joined the navy so they could one day take on Wetton. It was also during this time that Rapa Nui wrote the book about the Rainbow Nebula, which Robin had with him.
Pursuit of the Straw Hats
He was also present during the pursuit of the Straw Hats and stood on deck with the others. He also watched Rapa Nui accidentally sink a ship from his fleet, allowing the Straw Hats to escape. According to Rapa Nui, the new course was Ruluka.
Arrest of the criminals
Shortly after the The Going Merry emerged from the mist, Rapa Nui’s unit reappeared. The latter defeated Wetton and had his henchmen arrested. They revealed themselves, which pleased Henzo greatly. They also deliberately let the Straw Hat Pirates escape, claiming they had no more room on the ship.
