Kurumi Nonaka is a member of the Hero Clan in Japan and the younger sister of Yuki, making her the youngest child of Shuuya and Kaoru Nonaka. She is an Elemental Master with a strong connection with spirits.At first, she appeared as one of the three sent to eliminate Mio, upon joining the Toujou Household, she becomes one of the main female characters in the series. Kurumi is a petite young girl who is surprisingly developed for her age with blue-violet hair tied up in a ponytail most of the time using a white scrunchy and yellow eyes just like her older sister. Her battle outfit is tightly wrapped around her slim figure and it appears to be the typical attire for female Heroes, which consists of a navy blue leotard with a black collar and white skirt; and Kurumi also wears short tights underneath her skirt and a navy blue cape similar to her sister. All four of her limbs are covered by her spirit armor and her Spirit Gauntlet is also placed on her left forearm. Kurumi is first shown to be very protective of her older sister and is also dutiful to her position as a hero. She also held no sympathy for Basara after the incident from five years ago, even calling him a traitor due to a mixture of the grief that it caused her sister, protecting the daughter of the Demon Lord, despite her being initially being close to him thinking of Basara as an older brother. She didn't hesitate to attack Basara in their battle against one another, then even showed to be insulted after he didn't take her seriously as he used to blunt end of Brynhildr to attack her. However, after Basara saved her from falling and hearing his suffering as he slept upon being knocked out by Yuki, she realized that he was suffering most after the incident out of the three of them. Kurumi started referring to him as "Basara-oniichan" as she had done in the past. She quickly developed a close bond with those in the Toujou Residence, but Kurumi is described as having a certain innocence, which riles up the succubus instinct in Maria into the depths of depravity becoming both a sexual plaything for her yet close friend. This close proximity, however, it also forces her to confront her long-standing feeling for Basara, which at first caused her to shyly use her spirits to simulate a muted dream for her a couple of months in a row. Kurumi later starts to become jealous about the fact that Mio, Yuki, and later Zest were able to make a Master-Servant Pact with Basara. Then the actions of the Succubi Lucia and Shella forcibly brings these feelings to the surface by cursing her and making Basara subdue her, repeatedly. In Volume XII, she later starts to become more open and less shy about sexual interactions to where she started to do the same thing that Maria had done to her to Celis who ended up in the same situation as herself.

The Testament of Sister New Devil
Running into your new stepsister in the bathroom is not the best way to make a good first impression, which Basara Toujou learns the hard way. When his father suddenly brings home two beautiful girls and introduces them as his new siblings, he has no choice but to accept into his family the Naruse sisters: busty redhead Mio and petite silver-haired Maria. But when these seemingly normal girls reveal themselves as demons—Mio the former Demon Lord's only daughter and Maria her trusted succubus servant—Basara is forced to reveal himself as a former member of a clan of "Heroes," sworn enemies of the demons. However, having begun to care for his new sisters, Basara instead decides to protect them with his powers and forms a master-servant contract with Mio to keep watch over her. With the Heroes observing his every move and the constant threat of hostile demons, Basara has to do the impossible to protect his new family members. Moreover, the protector himself is hiding his own dark secret that still haunts him to this day...
