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. He also seems to wear a cocky grin on his face while his right hand is placed under his chin.

Personality
Takeruhiko seems to be a bit of a gentleman, as he said that a samurai from the Kina Kingdom cannot strike down girls.

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).

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), this form becomes deadly.

Nanaumi
They're relationship is not clear, however Nanaumi seems to adore Takeruhiko; when he appeared on the battlefield she squealed excitedly calling him "my lord" and adding that she had been waiting for him. Takeruhiko even asks if Naunami waited for him there "like a good girl".
