Hinahoho has a gigantic physique, like everyone of his race, with long blue hair, which is usually tied in a ponytail. He wears a blue bandana around his forehead. He also has amber colored eyes, and carries around a Rampaging Unicorn horn as a weapon. He also has light stubble on his chin.
Hinahoho has a kindhearted personality and cares about his kids a great deal. He loves kids so much, he even tries to get Sinbad to start his own family.
When he was young, Hinahoho was very timid, cowardice and often being a crybaby. He lacked courage on himself, to which even his little sister, Pipirika, treated him like a child, until he met Sinbad.
He came from the Extreme North's Unexplored Region and became a resident of Sindria under special circumstances. Hinahoho is a widower and has four children.
[Hinahoho] (currently unnamed) crashes into a boat in the middle of the sea. On the boat was a starving and thirsty boy named Sinbad. [Hinahoho] apologizes and shares some of his water with Sinbad. Sinbad thanks him and calls him a lifesaver. The Imuchakk cries as she says its been so long since he has heard thanks. Pipirika, [Hinahoho]'s sister, jumps on the boat and apologizes for her and her brother. Pipirika introduces them as people of the Imuchakk Tribe. Sinbad asks if everyone of their race have such big bodies. They agree, and [Hinahoho] says she's only 13 and he's 21. Sinbad asks for his name, but Pipirika says that he doesn't have a name yet. She informs Sinbad that other than the childhood name given at birth, to be given an adult name, a man of the Imuchakk must complete the coming of age ceremony.
She calls her brother miserable as "it" blew him away again. Sinbad asks what "it" is. She tells Sinbad that the coming of age ceremony of the Imuchakk is a test of courage against the Rampaging Unicorn. [Hinahoho] draws and explains that a Rampaging Unicorn is a huge type of fish. Pipirika is mad he draws better than her and says drawing is girlish and if he mans up, the girl he likes might turn and look at him. She explains that the girl is the top beauty of Imuchakk, and even if he wants to propose after the coming of age ceremony, it's futile. [Hinahoho] says that if he defeats a Rampaging Unicorn and become an admirable warrior, his affection will reach that person. He says until then he will not return to the village, and in order to propose he will work hard. Sinbad interrupts and asks if the monster attacking now is the Rampaging Unicorn.
[Hinahoho], Pipirika, and Sinbad agree to work together to beat the Rampaging Unicorn. The siblings explain to Sinbad about the Rampaging Unicorn. The fish's body is covered in hard coal, and has a distinctive long horn. Pipirika explains that the weapons they use are harpoons. She tells Sinbad that the Imuchakk is a tribe that takes pride in swimming, and that they seek battle with the Rampaging Unicorn in order to show ones proficiency in swimming, assessment of the situation underwater, and battle skill. She also explains that while [Hinahoho] is good at swimming, he lacks courage and hasn't stabbed the Rampaging Unicorn once. Sinbad comes up with the idea to use traps against the Rampaging Unicorn. [Hinahoho] says that in actual battle battle victory can be achieved from the combination of strength and wisdom. He then strongly says to Sinbad, "I beg of you, please lend me your wisdom."
Sinbad plan is to lead the Rampaging Unicorn. When Sinbad yells now, the two Imuchakk shoot arrows at it. They both jump into the water. [Hinahoho] thinks about the plan Sinbad made. The plan is to wrap the arrows in rope around a tree. This will uproot the trees and bring them into the ocean, and once there extend the battlefield by giving [Hinahoho] more footing. He uses it to jump high in the air and stab the Rampaging Unicorn. He is happy to have finally stabbed it with his harpoon. Pipirika warns him that he should quick as a storm is about to come, but he does not give up. He feels if he cant defeat the Rampaging Unicorn right now, no one will ever acknowledge him. He yells, "I won't be treated as a child. I've had enough!!" The Rampaging Unicorn throws [Hinahoho] off. Sinbad says that [Hinahoho]'s spirit has won him over, and uses Baal's power to finish it off.
[Hinahoho] and Pipirika are both astonished at how Sinbad finished it out. [Hinahoho] wonders if he can still say that it was him who defeated the Rampaging Unicorn, and if he's an adult now.
After a week, they all sett off toward Imuchakk. [Hinahoho] has also taken off the horn of the Rampaging Unicorn and is carrying it around. When they arrive back to Imuchakk, they are greeted by all of the Imuchakk. [Hinahoho]'s and Pipirika's father, one of the Patriarchs of the Imuchakk, greets his son upon his return.
When one of the Southern Creatures attacks Sindria, he stands alongside the rest of the Eight Generals and watches as Sharrkan defeats it. Then, he is present during the introduction of Alibaba Saluja to Sharrkan, but talks with someone. During the Mahrajan Festival, he takes a toast with the Eight Generals such as Ja'far, Drakon, Masrur and Sharrkan, but also with Sinbad and Alibaba. He is officially introduced to Alibaba, Aladdin and Morgiana by Sinbad. He appears out of nowhere, asking if Sinbad called for him. He is there with his children, who ask him if they can drink alcohol, to which he doesn't agree. When Drakon asks Sinbad if he's ever going to change his mind and marry a woman, Hinahoho says that he's right, as it's good to have brats around and advises Sinbad to have a lot of them.
After Sinbad and Alibaba are cursed by Ithnan, Hinahoho is in the room, along with the rest of the Eight Generals, staying close to Drakon, Masrur and Ja'far. When Sinbad says he's alright when he mentions only caring about Alibaba's curse, he doesn't seem surprised but stays silent. After the whole problem is solved, he sits during the meeting with Sinbad and the rest of his Generals, listening to the results of the last dungeon diving and to what Sinbad has to say.
Hinahoho stands with Ja'far and watches Sinbad and Kougyoku Ren's duel. He asks Ja'far what Sinbad has in his mind, wanting to show off his powers to a Metal Vessel user from an enemy country. However, when Sinbad Djinn Equips, he becomes worried, saying if Sinbad isn't doing so in front of so many people, even those from Kou. Seeing Kougyoku's Extreme Magic, Vainel Ganezza, he comments that if they were fighting a battle on the sea, Sindria's Navy would be destroyed with a single attack.
After the three year time skip, Sinbad abdicates his throne as king of Sindria and the other kings follow suit, becoming Board Directors for the International Alliance. Hinahoho along with Sharrkan, Pisti and Spartos return to their countries and become the new rulers.
As an Imuchakk, Hinahoho is naturally adept in swimming and fighting underwater. Being a member of the Imuchakk tribe, he is blessed with whale-like skin that reduces friction underwater, making him able to propel himself with minimal effort to the point that he appears to be "kicking" the water. Hinahoho also possesses eighty percent more protein in his muscles than average humans. These muscles are capable of storing more oxygen, enabling Hinahoho to hold his breath for over an hour.
Hinahoho has also shown proficiency when using bow and arrows as shown when he successfully ensnared the Rampaging Unicorn while completing his coming of age ceremony.
Hinahoho was born and raised in Imuchakk, a country covered in ice and snow located in the extreme north. Perhaps because of this, he is naturally resistant to cold weather.
Rampaging Unicorn's Horn
Like every warrior of the Imuchakk Tribe, Hinahoho carries around a large Rampaging Unicorn horn and uses it as a weapon.
Similar to other members of his tribe, Hinahoho uses a standard Imuchakk harpoon.
Hinahoho has the ability to use the Magoi within his body to entrust his Ki into his Rampaging Unicorn's Horn, however it seems to take him a long time in accumulating the magoi.
- Number One Harpoon: This is the greatest attack of the Imuchakk. Hinahoho manipulates his magoi into harpoon and then shoots it out at the enemy like a beam.
- Galfor Roromus (Frozen Sea of the Southwest): Hinahoho's Household Vessel is the rampaging unicorn's horn he has been using as a weapon. It appears as the head of a huge wolf made of ice with very sharp teeth, which throws itself at the opponent.
When Hinahoho first met Sinbad he was happy that Sinbad thought of him as nice (since in his homelad he was treated as "a fish left out to dry") and thinks Sinbad was an amazing person. However, he grew jealous of Sinbad's power and tried to capture the dungeon in his homeland. Through the course of the dungeon, Hinahoho began to truly respect Sinbad and gladly followed him as his "King". He believes Sinbad could change the world.
Even now, Hinahoho retains a friendly relationship with Sinbad, and tells him if he gets married to have lots of kids.
Hinahoho's little sister, who was always apologizing for her brother messing things up. Although she is shown to really care for her brother and wants him to do his best. Hinahoho also displays a protectiveness towards his sister when it appeared she had a crush on Sinbad.
