Description
Orca is a high-ranking military commander of the Skylos Empire in Children of the Whales, serving as the head of the empire's Apatheia corps and as the supreme commander of the battleship Skylos during its invasion of the Mud Whale. He is the older brother of Lykos, the girl discovered by Chakuro and taken in by the people of the Mud Whale. The siblings were separated when Lykos entered the empire's soldier training school at the age of seven. Physically, Orca is described as having brown skin, long bright hair, and a large distinctive mark on his face.

As an Apatheia, Orca is a soldier whose emotions have been stripped away, and he represents the empire's ideal of the emotionless operative. He is a composed, calculating strategist who carries out his orders with clinical efficiency and is fully committed to the empire's mission of eradicating the people of the Mud Whale, whom the empire condemns as the sinners of Falaina. On the surface, he can appear outgoing and sociable, and he is capable of being friendly with those whose ideals and values match his own, but this outward manner never interferes with his duty. His motivations are tied to the preservation of the empire's established order rather than to any personal vendetta, and his loyalty to that order is absolute.

His combat record is marked by a notable contradiction: Orca is personally described as unwilling to kill, yet he has killed more enemies than any other soldier in the imperial army, and his thymia is regarded as the strongest in that army. It is this record that earned him his two nicknames, Orca, taken from the killer whale, and the far less flattering God of Death.

Orca's most significant personal relationship is with his younger sister Lykos. Because Lykos regained her emotions after leaving the empire and chose to side with the Mud Whale, Orca sees her as a failure of the imperial system. He seeks to reclaim her and bring her back under imperial control, and if she cannot be reclaimed, he is prepared to destroy her. Where Lykos stands for emotion, connection, and individual choice, Orca embodies the empire's demand that its soldiers feel nothing and obey completely, and his relationship with her is defined by his effort to maintain control over her identity.

In the story, Orca acts as the primary antagonist of the Mud Whale conflict, commanding the empire's forces against the island's inhabitants. He is also the superior officer of Liontari, the unstable Apatheia soldier who carries out much of the fighting, and whose erratic violence contrasts with Orca's controlled methods. Orca's role is to embody the ideological wall that the protagonists must overcome, and his strategic mind, personal power, and unwavering loyalty to the empire make him a formidable obstacle to the Mud Whale's survival.

Within the events of the anime, Orca does not undergo a personal transformation. He remains a committed instrument of the empire throughout, and his development is defined less by change than by the consistent demonstration of his convictions, particularly in his dealings with Lykos, whose rejection of the empire he cannot accept even as her fate remains bound to his own.
