Kumi is a unique entity in the realm of succubi, as she does not possess the typical desires associated with her kind. Unlike her counterparts, she is not driven by the same insatiable needs, which sets her apart in a world often defined by such cravings. Additionally, she is not related to Akuma by blood, which adds another layer of complexity to her character. Kumi is known for her kindness and unwavering support, though her well-meaning nature can sometimes come off as slightly annoying to those around her. Despite her amiable disposition, she finds herself in a state of uncertainty regarding Akuma's whereabouts, and the thought of marriage is far from her mind at this stage in her life.

Gifted with mystical arcane star magic, Kumi possesses abilities that are as enchanting as they are formidable. She can soar through the night sky, gliding among the stars, and her musical talents allow her to create melodies that resonate with the cosmos. Furthermore, she has the extraordinary capability to conjure sharp stars that can slice through even the hardest of diamonds, showcasing her power and creativity. This magical prowess is a testament to her unique heritage, and it provides her with a sense of purpose and identity that transcends the typical expectations of a succubus.

Having once lived with her family, Kumi now shares a home with Akuma, seeking solace from the chaos of her past. She has distanced herself from the drama that often surrounded her, particularly the attention drawn by her mother, who proudly proclaimed her as the queen of succubi. This spotlight led to bullying is peers like Roxi, whom Kumi despises yet feels timid around. At 22 years old, Kumi yearns for a peaceful existence, free from the burdens of her lineage and the expectations that come with it. Her journey is one of self-discovery, as she navigates the complexities of her identity while striving for a tranquil life away from the shadows of her past.

The Iron Maidens are the most feared protectors of the Enbi family. Though they appear to be ordinary maids tasked with maintaining the sacred Enbi Sanctuary, their elegant uniforms conceal a far darker purpose. Each Maiden is a highly trained executioner capable of eliminating entire armies through unmatched skill and relentless determination.

Since their creation, the five Iron Maidens have demonstrated power that eclipses even the renowned Luminous Clan. Bound by absolute loyalty to the Enbi family, they act as guardians, cleaners, spies, and assassins. Once an enemy is marked for extermination, the Maidens pursue their target without mercy, earning a reputation as bloodthirsty hunters whose mission ends only with complete victory.

To outsiders, they are servants. To their enemies, they are a nightmare in lace and steel.
