Two humans with identical genetic makeup will attract and find each other, no matter how far apart. And those drawn-together clones will enter into a mutual battle of extermination. “The laws of magnetism” and “survival of the fittest” clash the moment these clones are pulled together, leading to crafty scheming and high-stakes competition in what turns out to be the ultimate game of “musical chairs” played out by clones yearning for distinction as “the true one.”

In the year 2060, a failed science experiment has brought about a barren, famine-plagued world where “flowers” no longer bloom. While recovery efforts show promise, District 7 - ground zero for the accident - has been left to its own devices, exempt from reconstruction as “an abandoned city.” One resident of District 7 is Ai, an angelic-looking young girl who hides a darker face. As member of a team of assassins called “Last Garden,” she is a coldhearted killer who carries out her assignments with faithful precision. Her life now roiled by a bizarre fate, this lone woman assassin must simply learn to survive.

Yuko is a biology teacher and education counselor at a local high school. Between the school bell chimes, she’s an ordinary teacher with superlative instructional technique. But when school lets out, she transforms into the one person you don’t want to mess with, a super problem-solving mercenary for whom no method is off limits when it comes to rooting out the myriad problems infesting teenage life in the schools. With an “eye for an eye” approach, she’s not above breaking a few laws and demands payment for her services. Enlisting as her sidekicks, Sumire and Aya, the personality-diverse trio run their elite “extra-curricular social work” club unified around Yuko’s charismatic leadership. High school students do not live in a sanitized bubble, and some extraordinary problems require extraordinary solutions that black-and-white rules of propriety or common sense alone cannot solve.

By day, Shio manages an aromatherapy salon. But by night, she is the owner of “Striped Sheep”, a business that dispatches men to the homes of women who suffer from insomnia to lie next to them. These “Striped Sheep” in fact represent a brand new profession of so-called “co-sleepers,” whose sole mission is to provide a night of relaxation to restless women. Shio’s four “sheep” consist of Gai, her ex-husband’s brother, Ran, a man with a cool, soothing gaze, the glib Linda and a taciturn book worm named Matthew. As sleep-sharers, these four men find out a lot about what drives or plagues their women clients, and help them gradually discover themselves and the right life pathways. “There are nights when a woman just needs a man at her side.”
