Takeruhiko Yamato

Takeruhiko Yamato (倭 健彦, Yamato Takeruhiko) is the King of the Kina Kingdom, one of the countries that form the Seven Seas Alliance.

Appearance
Takeruhiko appears in Japanese-styled armor, wielding a large katana behind him. He has black hair that spikes up that's crowned by a headgear with horns that make him appear to look like a demon.

Personality
Takeruhiko seems to be a bit of a gentleman, as he said that a samurai from the Kina Kingdom cannot strike down girls. However, he also seems to be ambitious and war-loving, as he quickly brushes that attitude and strikes down Koumei despite the long distance between them.

Kou Empire Arc
Takeruhiko sends his servant Nanaumi to entreat Hakuryuu.

Takeruhiko and Darius Leoxses come to Hakuryuu's aid and stand in the way of Kouha and Kougyoku. He comments how the fight would be a bit of a dilemma seeing as a samurai from his kingdom cannot strike down girls (accidentally mistaking Kouha for a female). Takeruhiko presents himself, and, when questioned by Kouha why is the king of the Kina Kingdom is meddling with the Kou Empire's civil war, both Takeruhiko and Darius proclaim that the kings have come to the aid of a sworn friend of the Seven Seas Alliance

Both Takeruhiko and Darius introduce themselves again, and Kouha is surprised to know that even the Kina Kingdom is part of the Seven Seas Alliance. When Hakuryuu joins them both, Kougyoku questions this, prepared to attack, but Kouha stops her. He then asks why is the Seven Seas Alliance invading the Kou Empire's territory, due to their belief in "not to invade and not to be invaded", but Darius brushes it off saying they've come to stop the conflict in the territory of their sworn friend. Darius then says that they've come to the side of the true commander of the Kou Empire, Hakuryuu, and explains that the Kou Empire made a vow to the Seven Seas Alliance and became their ally, surprising Kouha and Kougyoku.

Kouha realizes the true meaning of the war, and explains to Kougyoku that it was all a pretext for the Seven Seas Alliance's intervention, and Kougyoku, realizing the Alliance's leaders were watching all along, says that's cowardice. Takeruhiko says he honestly didn't like how that man handed things, but Darius says that complaints aside, Takeruhiko should carry out the orders given to him without failure. Takeruhiko says he understands, and proclaims that he shall take the head of the enemy general, unsheathing his sword and activating his Djinn Equip. Kouha and Kougyoku quickly assume his target is Kouha, but he ignores them and strikes Koumei, using his Djinn's ability to quickly reduce the distance between them.

Abilities
He seems to be able to control water, as he rode a large wave towards the battlefield, even when they were in the middle of the plains.

Metal Vessel
Caim is the Djinn that Takeruhiko obtained when he conquered the 53rd Dungeon. Caim is the Djinn of Listening Closely and Absolute Sharpness. The Djinn dwells in the long katana which he carries.
 * Djinn Equip: In this form, he is able to slash his enemies from very long distances with high precision and accuracy. Combined with special swordsmanship of Kina Kingdom, One-Hit Kill Technique (一撃必殺, Ichigeki Hitsusatsu, "one blow certain kill"), this form becomes deadly.

Nanaumi
Their relationship is not clear, but Nanaumi seems to worship Takeruhiko, as when he appeared on the battlefield she squealed and excitedly called him "my lord", and added that she had been waiting for him. Takeruhiko even asks if Nanaumi waited for him there "like a good girl".
