'Seiran Fellowship' is a secret clan formed by heiresses of corporate conglomerates. Taking an empty garage in an upscale residential area of Chuo Ward as their domain, they carry out secret activities for their own motives. Currently revealed members of the Seiran Fellowship clan include Runa, Mayoi, and Ren.

Mitsukoe Runa is the only daughter of the real estate tycoon family, the Mitsukoe family. As a young lady of a family that became ultra-wealthy due to a massive real estate boom, she was not born into wealth. Conflict arose between her grandfather, who wanted to preserve his identity as a commoner despite his wealth, and her father, who wanted to live as a rich man. Raised by her grandfather until his passing when she was in the third grade, Runa then moved into her father's home to begin her life in earnest as an heiress. Runa deeply treasures her memories of her grandfather and somehow has a weak spot for older, mature men. She is also convinced that in about 10 years, the Shunin will be exactly her type.

Keikou Mayoi is an heiress from a corporate family ranking in Japan's top 10 conglomerates. Befitting a young lady of a wealthy corporate dynasty, she wields gem magic that evaporates expensive jewels without a second thought. Although she wears dental braces, she is not self-conscious about them at all, displaying a slightly rude and unabashed attitude toward others. However, she knows how to draw boundaries in relationships and, surprisingly, shows a polite and thoughtful demeanor when the situation calls for it.

Shiranui Ren shares a complex relationship with Runa and Mayoi, acting as their supporter, errand-runner, and friend. In reality, she is a bodyguard and hitman dispatched by the Mitsukoe and Keikou families. While she sometimes appears to struggle with communication anxiety, she maintains an air of deep mystery in many respects. Strangely, when looking at the Shunin, she occasionally makes a subtle, predatory expression.
