Kiro

From Kokorodatabase

Kiro is the oldest child of Namine and Riku, having a younger sister, Morie. He's thirteen, and is a mage of sorts with power over the element of twilight, which is technically a blend of darkness and light, and uses twin blades in battle, as he is not a keyblade bearer. It should also be noted that Kiro is known as a 'bottomless pit', mainly because of his love when it comes to food. Ironically, both he and Kitenshi Kocha were able to defeat a Black Sin member, Meitou Kale, by using their common love of food.

Kiro first appeared in Kokoro to bother Kyr as he had done to the Mirror counterpart, pnly to realize that the Kyr here wasn't around in the cafe too much. He comes in occasionally to visit Kocha and Kale. Otherwise, he's mainly in Mirror or his home dimension of Kingdom Chronicles.

Trivia

• It should be noted that Kiro really doesn't have a surname, as Riku's surname was never stated in canon, but his counterpart in Kokoro does, hence why he's referred to as Shimarano Kiro.
• Kiro normally doesn't have wings, nor does he show them off. They were a result from his days working from the darkness, and were left as a mark that he rarely discusses. The other mark is his weak ability to control the heartless, but as it's rarely used, it's currently dormant.
