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

'Mitsukoe Runa' is the only daughter of the Mitsukoe family, a real estate conglomerate. She is a young lady from a family that became ultra-wealthy due to a massive real estate boom, but she was not originally born into wealth. There was a conflict between her grandfather, who was rich yet tried to maintain his identity as a commoner, and her father, who wanted to live like a rich man. Runa was raised by her grandfather until he passed away when she was in the third grade of elementary school, after which she moved into her father's house and truly began her life as an heiress. Runa cherishes her memories with her grandfather and somehow has a soft spot for mature, older men. She is also confident that in about 10 years, the Chief will become just her type.

'Keikou Mayoi' is an heiress from a corporate family ranking in Japan's top 10 business dynasties. Fitting for a wealthy heiress, she uses gem magic that freely vaporizes expensive jewels. Though she wears dental braces, she is not self-conscious about them at all and shows a somewhat impolite, unreserved attitude toward others. However, she knows how to draw the line in relationships and unexpectedly exhibits polite, thoughtful behavior when the situation calls for it.

'Shiranui Ren' shares a complex relationship with Runa and Mayoi as their supporter, errand runner, and friend. In reality, she is a bodyguard-slash-hitman dispatched by the Mitsukoe and Keikou families. Although she seems to suffer from social anxiety that makes communicating with people difficult, she presents an aura surrounded by many secrets. Peculiarly, when looking at the Chief, she occasionally wears a subtle, predatory expression like that of a carnivore.
