7 Seeds

7 Seeds

Scientists had predicted this disaster, and in response, the leaders of every country met to develop a plan for human survival before the meteor hit. The Seven Seeds project was developed out of this meeting. Each country froze a number of young healthy people, which allowed them to survive the meteor. After the computer determined that Earth was once again safe for human life, it released them into the world. The Japanese government created five groups of survivors: Winter group, Spring group, Summer group A, Summer group B, and Fall group. Each group consisted of seven members and one guide. The guide carried small tubes of poison on their necks to allow them to end their lives if their situation became unbearable. The Japanese government prepared seven "Fuji" as refuges for the groups. In each Fuji, the group would find seeds and numerous books instructing them on survival in the wilderness.

Satou Atsushi isn't neglected by his family so much as ignored completely. Left to fend for himself, Atsushi fails to learn human speech and instead learns "cat language" and "Dog language" from the family pets. When he's eventually socialized with other children, his speech is stunted and his social graces leave something to be desired. But on his first day of nursery school, he meets a gloomy blonde with the same last name who seems to be a safe enough choice in a first friend. After developing a rather sizeable fixation with Satou Manato, he finds out that there his first friend is seriously ill and has a twin; Shuuto. Years later, two other friends begin school and find that there are two Satous in their class too. Two Satous who, at first glance, could easily be mistaken for twins, but there's a bit more to things than it first appears...

At first glance Moolchi is just another shy, unassuming boy whose greatest talents are running away from bullies and binging on vitamin supplements. Then one day, Moolchi's absentee father sends him a most unusual gift--a stunningly-proportioned automaton. She calls herself "Six" and mumbles about having a "prime directive." This strange and exquisite creature quickly turns the boy's life upside-down, violently disposing of high school hooligans and anybody else who gets in his or her way. The word "oblivious" barely does him justice as Moolchi remains blissfully unaware of his father's dangerous double-life, or the cute hall monitor who harbors a crush on him, or the intentions of this mysterious femme fatale who insists on bathing with him. Meanwhile, ominous storm clouds gather on the horizon, and one lingering question looms above the others "who is this so-called "Zero" that everybody is looking for?
