Haimaru

Haimaru (ハイマル, Haimaru) is the eldest child of and the twin of Haimaru. He was born not long before his father was killed, and once he was, Haimaru, along with his sister Raimie, was sent away to a far-distant planet to escape the bloodshed of the Planet Trade Organization civil war. Because of this, Haimaru was not an active member of the organization, despite him being the rightful king of the Planet Trade Organization.

Trivia

 * Like all Arcosians, Haimaru's name is a pun on something cold. His name is a pun on the word "hiemal".
 * Following the inheritance laws of the Planet Trade Organization, Haimaru was the rightful king of the empire after his father Cooler died. Of course, due to his young age at the time of the Planet Trade Organization civil war and his presumed disappearance/death, other members of his family ignored his claim.
