Although Ky's skills remain as sharp as back then, his sense of honor prevents him from using war-time tactics in duels. Once a merciless enemy to all Gears, he actively wishes to move on from the "killing machine" that he was during the Crusades, and leave his hatred behind. However, he was forged by war such that Justice once remarked that Ky had the "eyes of someone who knew nothing yet but battle". Ky is firmly committed to the public good and to bringing hope to others, and treasures peace above all. Initially conflicted by the appointment, the throne made Ky lose the old shine he had as a youth, but he has since increasingly defied conventions, being the "problem child" according to Leo.

Becoming king prior to Overture also made him lose some of his zeal -his view has since broadened significantly, and has learned to see the world from the perspective of others.

Īlthough Ky's strong beliefs once tended to color his moral world black and white, realizing that his 'justice' was limited to human convenience and that no single truth governed everything was a significant blow to his identity. Ky himself knows that his idealistic dreams can never come true, but he will try regardless. His dogged pursuit for justice and fairness has upset more than a few in power, as he is willing to confront his superiors if he believes them to be corrupt. While others may mock Ky for his idealism (especially Sol), he has the determination to live life according to what he believes in. He is also a "hot-blooded fool", prone to taking rash actions when angered. On the other hand, Ky can be notoriously inflexible and is easily disgusted by those who disturb the peace, having a complex about freedom even if he doesn't realize it. He is also chivalrous, being known to hold back against female opponents, and is utterly dedicated to protecting the weak. Of a straightforward and serious personality, Ky is kind-hearted, charismatic, honest, diligent, polite, and believes in fair play. Ky is a religious man, the adjective describing both his devotion to God, as well as his commitment to the ideals of justice, order, and honor. Attached to his brown waistbelts is a scabbard wherein he keeps the Thunderseal sheathed.

In Strive, his outfit consists of simple dark blue trousers and dark brown boots, a single-sleeved V-neck dark blue shirt with lapels, a cape-like white jacket over his shoulders, and blue gloves with metal plates on the backhand. In Xrd, he returns to a modified Holy Order uniform, much more form-fitting than before. In Overture, he sports instead a elaborate rolled-up longcoat with two big belts as well as a blue cloak, while keeping his color scheme. Ky invariably wears fingerless gloves, either black or blue. It is fastened together by a belt buckle inscribed with the word "HOPE". His usual outfit is a loosely-fitting, blue base version of the white uniform worn by the Sacred Order of Holy Knights that consists of white trousers and shirt below a white longcoat its knee-length front resembles a blue cross and has a white elbow-length cape.

His hair has grown in the timeline of the series, to the point where he sports a ponytail in the Xrd games, although he goes back to a short hairstyle in Strive. Ky is a handsome young man with blond hair and blue eyes.
