He is a ruthless and evil king. The Cat King kidnaps Haru Yoshioka and brings her to the Cat Kingdom, where she is transformed into a cat. When Prince Lune informs him that he already had a bride called Yuki, the King then tried to marry Haru himself, which she refused to do. When he chases her, he fights the Baron Humbert von Gikkingen in a sword fight, which he loses, having both his gem eye shattered and his lowered half shaved off. His last appearance is on the ledge, where he tells his aide that he would like to retire.
