Leader of the Sons of Calydon. Real name: Caesar King. Gender: Female. Height: 176cm. Appearance: High side-ponytail on the left. Light green hair and golden eyes. Voluminous and wild look. Her left arm is a prosthetic. Weapons: An ether-alloy sword named "Veni" and a transforming ether-alloy shield named "Vidi." Personality: Straightforward, cheerful, and full of chivalrous spirit. She tends to rush in headfirst without thinking about the consequences. While she often struggles with complex discussions, it's mostly because she avoids tedious mental labor; her intuition and cognitive abilities are actually very high. She shows her spiritual qualities as a leader by noticing the concerns of her members and reciprocating their care, prioritizing the lives of the people over personal feelings or pride, and setting clear community management policies as the new Overlord. She leaves almost all the brainwork to Lucy, while she herself rides her bike into battle with sword and shield to protect residents and cargo from outlaws and Ethereals. On the other hand, she has a girlish side, enjoying romance movies and shojo manga, though she gets embarrassed and tries to hide it if others find out. Pure-hearted.

The three dog tags he wears belong to comrades who died in the line of duty during his mercenary days. Personality: He has a cynical, nihilistic attitude but is surprisingly good-natured. He's the straight man in the current Calydon, which is full of eccentric women. Since the leader always charges in first, he often ends up in a support role. That said, he likes Caesar and the others and considers the group a good place to belong. He often joins in their wild antics while maintaining a cool demeanor, which leaves Lucy to deal with the fallout. He is naturally sweet when it comes to romance with someone he trusts. He pulls off handsome moves and lines that would surprise even a shojo manga. While watching a romance movie together, he might say something like "I'd like to try that" during a kiss scene. Background: He once formed a mercenary group providing escort services in the Outer Rim, but lost three comrades during a mission. Feeling responsible, he disbanded the group and paid massive compensation to the families of his fallen comrades, even going into debt.
