Tenko is voiced by Kira Buckland

Kirumi is a tall, thin young woman with pale, desatured green hair and bangs that obscure her left eye (Though sometimes it can be seen when expressing certain emotions). Her eyes are green and her maid outfit consists of a black button up pinafore with a spiderweb motif, a white dress with a black collar, and a purple tie. She wears a black headband that is commonly worn by a maid. She wears black gloves with silver rings attached, black tights, and also wears black shoes with white laces and heels. Her dress also has black lace attached to the bottom of her skirt.

Kirumi is a refined, mature young lady who's 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 capable of being independent and do 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 and level-headed. [6] Her intelligence can be shown when she is speculating. Her speculations are provided with a fact and thus they are quite hard to refute—for example, when she accused Gonta Gokuhara as the culprit of Rantaro Amami's murder case everyone believed in her well-thought, descriptive accusation until Kaede Akamatsu objected it with a solid evidence. In Chapter 2, when the students discovered the half hallway of 2nd floor and the third floor, she felt that no one had set foot on the academy for a quite long time based on small details, and when she found out that the rooms of the deceased are locked by Monokuma, she thought that it was needed to be done in order to secure Rantaro's belongings, since Monokuma himself mentioned that he may have had a hunch about the truth behind the Killing Game.
