3★ A mercenary fond of sarcasm and complaining. Since Ryuka will take any job without much concern for the details, he's called a "vulture" by those who work with him. He currently works for the Aldore military in Crystallis, carrying out his assigned missions while complaining about the base's food quality on a daily basis.

4★ A mercenary working for the Aldore military who seems bored of everything, as if he's given up. Ryuka was once part of a vigilante organization that courageously fought against the Aldore army in a certain region until he suddenly left one day. He never spoke to his best friend after his departure, but their memories together often torment him in his sleep.
