Takahiro Aka

Takahiro is Akane's husband and Kyoko's father.

Background
Takahiro came from a long line of men who served in the Rainbow Knight Force; to continue that line, his father forced him to join the ranks as soon as he turned 16. During his first training session, however, it quickly becomes clear that he is very clumsy with a sword, and he worries about his lack of talent bringing shame to his family. He was soon approached by Akane, then the princess of the Red Kingdom, who offered to help him with his training. These extra training sessions allowed Takahiro to become more skilled with the sword, and he became grateful to Akane; he also started to fall in love with her, but because of her status as a princess, he feels as though she is unobtainable. When the first Rainbow War occurred, he fought the hardest out of any of the other Rainbow Knights, and after the war was over, he approached the Red King and Queen, asking for Akane's hand in marriage. The King and Queen are hesitant at first, but when they use the "Red String of Fate" spell to determine Akane's soulmate, it is revealed to, indeed, be Takahiro; years later, the two marry, and Takahiro becomes the Red King while Akane becomes the Red Queen. Akane and Takahiro soon try to have a child, but because of Akumi taking residence in Akane's womb (which is something that neither of them know about), each pregnancy ends with a miscarriage. Finally, the couple decides one more time to have a child, and this time, they are able to give birth to a happy and healthy baby girl - Kyoko.
