Ky is a deeply religious man, the adjective describing both his devotion to God, as well as his commitment to the ideals of law, order, and honor. He is diligent and scrupulous. However, despite his great faith and strong conviction, he is not beyond doubt, and is not entirely incapable of seeing the colors between black and white. Loyal to his ideas more than his surroundings, Ky will not hesitate to investigate his superiors if he believes them to be undermining his conceptions of justice. He is a compassionate man and chivalrous in the classical way, being known to hold back against female opponents if he is forced to fight them. Though his strong beliefs tend to color his moral world black and white, his experiences have developed his character beyond this caricature.
In his Overture profile, it is stated that his position as a king made him lose some of his zeal, but he gains a new perspective over things in its place.
In Guilty GearEdit
Ky Kiske is the current captain of the International Police Force (IPF). Charismatic and highly talented with both swords and magic, he was the former commander of the Sacred Order of Holy Knights (Seikishidan) during the Holy War (2074-2175 AD) that was fought between mankind and the Gears (the latter under the leadership of Commander Gear Justice).
Orphaned at a young age during the war, he met the then-commander of the Sacred Order, Kliff Undersn. Afterward, Ky was told to come back after five years of training to see him again if he really wanted to fight. Five years passed, and Ky returned, ready to do battle.
A year passed and due to the retirement of Kliff, 16-year-old Ky Kiske was recognized for his talent and named the new chief of the Sacred Order. With the appointment, he was given the Thunderseal, a weapon that allowed the wielder to manipulate the difficult element of lightning, and one of the Sacred Order's holiest treasures. Soon after his appointment, he led the Knights to victory, and ended the 100-year genocidal war. The Order was disbanded after the Holy War ended.
Five years later, Ky entered the IPF. He was soon promoted to rank of captain. However, he is considered easily controllable, and is manipulated by higher powers who were unseen players from the Holy War.
After Ky hears rumors of bloodshed, huge prizes, and the possible resurrection of Justice, Ky Kiske enters a tournament that will select members for a second Sacred Order of Holy Knights.
Guilty Gear XEdit
After hearing Justice's last words at the conclusion of the tournament, Ky hears new rumors, these ones of a new Commander Gear that doesn't wish to harm humans. He sets out to find the truth in Justice's final words and the flaws within his own concept of justice.
Guilty Gear XXEdit
After rescuing a beaten Commander Gear Dizzy and entrusting her to Johnny's care, Ky returns to his normal duties as a captain of the IPF. As soon as he is returned to work, Ky Kiske is thrust into a new conspiracy which includes robot clones of himself, a secret organization, a woman in red named I-No, and his bitter rival, Sol Badguy.
Guilty Gear XX Λccent Core PlusEdit
Ky investigates the Post-War Administration Bureau and fights its minions, ultimately separating from the police but continuing his labor as a banner of justice. He later helps out Dizzy control her power, and protects her. The two grow close to one another, marking the beginning of their romantic relationship.
Depending on if players defeated Dizzy with an Instant Kill or not, Ky will either look after Dizzy, leading into his Path 1 ending, or he will leave Dizzy in Johnny and May's care again before going his own way (Path 2).
Guilty Gear 2: OvertureEdit
Ky has assumed the position of king, reigning over the land of Illyria, armed with the sword Aquila, as he is keeping his lover sealed with the use of the Thunderseal's power. Having grown much more mature and composed over the years, his rivalry and animosity towards Sol has diminished entirely, having entrusted to him his part-Gear son, Sin. Ky is shown at constant conflict towards his own ineptitude of being a father and a husband, due to the racial issues regarding Gears. His relation with his son Sin is not quite close as well, as Sin is shown calling his father a "shitty king".
Story of Joining Sora's TeamEdit
While the team members go solo, and Riku meets Sol Badguy, Ky Kiske meets Sora and the four team up to find the Keyhole and stop their enemies from taking over the worlds. Soon after they received a message from Kairi, who was with Dizzy, told them that the Keyhole was located in Black Tech. When everyone met up, they all came face-to-face with I-No, Pete, Valentine, Maleficent, That Man and Big Yellow, and had a showdown which lasted about 203 seconds. After the showdown, and the Keyhole was unlocked, Ky Kiske and his friends joined the team to stop their enemies and save their world.
