Poor but proud brother and sister Mihato and Ren Uesugi flee from their drunken father in a remote province to the big city in search of happiness and a new life. After parting ways, they set out to find work, and, of course, honest and courageous Ren immediately rescues a light‑haired "loli" with two long ponytails who is indifferent to the rest of the world. Thus our heroes find themselves in a manor, serving three sisters of the Kuondzi family. The eldest—Sinra—is a talented conductor who loves to manipulate everyone around her; she is absolutely unselfconscious. The middle one, already mentioned Miya, is a family genius with an IQ of 240, a university‑educated woman who, to put it mildly, looks far younger than her age. There is also a schoolgirl Yume who dreams of standing out against the brilliant older sisters. Naturally, at the Kuondzi estate there is already a stern butler, an impetuous maid, and a loyal bodyguard, and everyone lives with the household as one big, close‑knit family. No one would doubt that the newcomers, after enduring harsh trials and amusing adventures, will find their place in this new family, while along the way all the tropes of the "servants and masters" genre will be played out with references to many other anime and even Japanese history.
