Lykos is one of the main characters in Children of the Whales. She is a former emotionless soldier of the Allied Empire, who later defects to protect people of the Mud Whale.
At first, she seemed very emotionless, as a former apátheia soldier. But as the effects of the Nous wear off on his, she begins to show more and more emotions. She's introverted and self-reliant, having fought and survived for a long time on her own. However, she also cares for the people from the Mud Whale and has a soft spot for Chakuro.
When she was seven years old, her parents enrolled her in a military academy. Right before the start of the series, the ship she was on was attacked by a force hostile to the Allied Empire, and all of the others on the ship were killed.
