Kiritaka Muse (キリタカ・ミューズ) is a trade representative of Priestella and the successor of the Muse Trading Company. He is the last survivor of the Priestellan Council of Ten.
Making his debut in the opening volume of Arc 5, Kirataka played a passive, yet rather strong supporting role throughout the whole Arc, as he influenced many events, including the outcome of the battle against Gluttony.
Kiritaka has pale gold hair that's carefully smoothed toward the back of his head. He has a tall and thin body and wears well tailored clothes with a limited amount of adornments which make him look refined.
As one of the major merchants of Priestella, Kirita has a sense of dignity and self worth, and is shown to be educated based on his words and actions. He is skilled as a merchant, making him constantly busy. Every morning, he uses the Loudspeaker Meteor in the city center building to broadcast in order to let the citizens know that it would be used in emergencies.
Kiritaka has a strange obsession with younger girls and puts emphasis in whether a woman looks young rather than their actual age or mentality. Currently, he claims that his heart has been stolen by Liliana Masquerade, and tends to get out of control when things involve her, such as the time he attacked Subaru when he saw him with conversing with her.
Despite these qualities, Kiritaka is shown to have honourable qualities, as he nearly met his end, sacrificing himself to let Otto escape when Priestella was under attack.
White Dragon's Scale (白竜の鱗 Hakuryuu no Uroko): Kiritaka has hired the mercenary group called White Dragon's Scale, to be his personal bodyguards. The group consists of highly-skilled individuals, who are more than capable of protecting Kiritaka, when needed. During the fight with the Sin Archbishop of Gluttony, most of the members had their names eaten and were put in suspended animation, with Dynas being the only surviving member of the group. Following Lye's death, it's unknown if they have already regained their names.
