Kiryu is a calm and gentle young man who always wears a faint smile and rarely shows anger. He’s considerate and quick to help others, adjusting his behavior to fit any situation. He despises those who mistreat or underestimate girls and considers traditional gender roles outdated. Closely attached to his phone, he dislikes old-fashioned thinking and prefers to approach problems through understanding rather than conflict.

Despite his pacifistic nature, Kiryu can become protective and even intimidating, especially when it comes to his older sister, Akari. The mistreatment she suffered from their father deeply influenced his views on gender and discrimination. Like Akari, he hides his true emotions behind a cheerful demeanor. Due to conflicting beliefs, he lives apart from his father and brothers, unafraid to stand up to them or respond with sarcasm. Although he disliked the mandatory training imposed on all men in his family, he took it seriously to become strong enough to protect his sister.
