The Ultimate Maid. Kirumi is a refined, mature young lady who is described as "a professional who does a perfect job". She has a keen mind and she is talented in various ways, reportedly able to carry out any job, as well as being capable of independence and doing things on her own. She is polite and formal, as well as quite serious, and very willing to use all of her power to cooperate with the other students. She is intelligent, observant, and level-headed. As a maid, Kirumi's creed is "selfless devotion". Thus, she has a very strong sense of duty and a will to work for the sake of others even during the Killing Game. She voluntarily does housework such as cleaning and preparing meals for the students, even making sure each time that there's both Japanese and Western cuisine. Because of this, the other students seem to have strong trust in her, and she tends to wait outside the dormitory in case anyone has any requests for her. She is also shown to be very considerate and often asks the others if they are doing all right and gives them some advice. On the other hand, Kirumi lacks the concept of doing something for herself, and for her even to have a conversation is a request. She believes her own opinions hold no importance. For the sake of the people who need her, Kirumi is willing to do some immoral acts like murder and manipulation if it is necessary in her mind. She is willing to bear the burden of being seen as evil for the sake of her nation and its people.
