7 Seeds (7SEEDS セブンシーズ Sebun Shīzu?) is a Japanese science fiction manga series written and illustrated by Yumi Tamura. It has been published by Shogakukan since 2001, first in the magazine Betsucomi, then in Flowers. The series is set in a post-apocalyptic future, long enough after a meteorite hits Earth that new species have evolved, and follows the struggles of five groups of young adults to survive after they are revived from cryonic preservation. The title comes from seven caches of supplies, called "seeds", laid down by the Japanese government. In 2007, the series won the Shogakukan Manga Award for shōjo manga.

Story[edit]

When astronomers predict that the Earth will be hit by a meteorite, the world leaders meet to develop a plan for human survival called the Seven Seeds project. Each country will cryonically preserve a number of healthy young people, which will allow them to survive the devastation of the impact. After a computer determines that Earth is once again safe for human life, it will revive each group.

The Japanese government creates five groups of survivors named Winter, Spring, Summer A, Summer B, and Fall. Each group consists of seven members, who are not told about what will happen before they are put in cryonic preservation, and one adult guide who is trained in wilderness survival. These groups are scattered across Japan: the Summer groups in southern and northern Kyūshū, Fall in western Honshū, Spring in central Honshū near Tokyo, and Winter in Hokkaidō. The project also prepares sealed caches containing seeds and instructional books near the "seven Fuji". These seven Fuji are not related to the famous Mount Fuji, but are regional landmarks also named Fuji:

Awoken from the cryogenic sleep many years later, the young men and women find themselves amidst an hostile environment bare of any human life. Their former home country Japan has greatly changed. Completely alone, they can depend only on themselves to survive in the new world.

Characters[edit]

Every member of a group has a name containing a kigo, a poetic seasonal word, related to the group name — for example, all of the members of the Spring group have names traditionally associated with spring. Each group consists of seven members plus a guide trained in wilderness survival. The five groups are listed in order of appearance in the series, which is different from the order in which they were revived from cryonic preservation in the series' chronology.

Summer group B[edit]

Summer group B is created after the other four Japanese groups as a backup and consists of people who are healthy but rebellious or otherwise not well-adjusted to society. They emerge from cryonic preservation at the start of the series near an island in the East China Sea off the coast of Nagasaki Prefecture in western Kyūshū, and travel to the seed cache at the foot of Bungo Fuji in Ōita Prefecture.

Summer group A[edit]

The members of Summer group A were specially chosen for the Seven Seeds Project by the Japanese government. This project genetically engineered and conceived about 100 babies, born from carefully selected egg cells and sperms. Because of this, none of the members of Summer group A have a family name. These babies are raised on an island and taught wilderness survival until they reach the age of 17. At that time, a last test is carried out to select the seven that are put in cryonic preservation.

"Failures" or dropouts from this project are said to have left the island to join the rest of society, but it is revealed that they are actually killed and disposed of. Each child is instructed in seven classes of technologies: water, fire, wind, earth, plant, animal, and medical, and at age 13, they choose two classes to specialize in. In the end, one survivor is selected to represent each class. They emerge from cryonic preservation in the Pacific Ocean off the coast of southern Kyūshū, a little later than Spring Group.

Ango (安吾?)
A specialist in fire and water classes and the main character of the chapters about Summer group A. He is the top student of the project and a rival of Ryou's. He and Ryou reluctantly respect each other. Ango was attracted to Ayu previously. He is close friends with Koruri, Mayu, Nobara, and Shigeru. Ango unconsciously sees Natsu as Shigeru because of their similar timid personalities and hard-working nature. He has now learned to be a bit more open, possibly due to the influence of Team Summer B.

Ryou ( Ryō?)
A specialist in fire and water classes. Ryou is a top student and Ango's rival. He is depicted as rebellious with a cold demeanor, capable of evaluating situations dispassionately, but he shows glimpses of compassion at times. Though he may not seem like it on the surface, Ryou cares a lot about Ango, and seems to have developed a funny bond with Semimaru, where the latter refers to him as "Sensei" due to his extensive knowledge and survival skills. Ryou means cool.
Ayu (あゆ?)
Also known as Madonna for her beauty, Ayu is the best specialist in the plant class and also specializes in earth classes. She is sometimes bullied by other girls because they are jealous of her appearance and the attention she attracts from boys. She looks down on other human beings, frequently referring to them as idiots and filthy creatures. She now owns a small hyper black dog named "Kuroda" given by Aramaki, and is shown to be quite fond of him. Her interactions with Aramaki seem to have positive effects on her, as she is shown trying to understand Aramaki's views, and has no doubt developed an admiration for Aramaki. Ayu means sweetfish.

A specialist in animal and plant classes. Gengorou is depicted as a kind and mature person. He and Ango respect each other as peers.
Ban (?)
A specialist in animal and medical classes. Ban is depicted as slow and socially awkward, but he is quick on his feet when treating an injured person.
Nijiko (虹子?)
A specialist in earth and water classes, Nijiko is depicted as always being calm and collected. She is with Ryou, but appears to not truly care for him. Aside from getting along decently with Ryo, Nijiko seems to grudgingly respect Ran.
Unami (卯浪?)
The guide of Summer group A. He is an overpowering jerk and has no qualms about hitting his students. After their revival in chapter 50, he becomes the target of revenge by Summer group A and is killed by all members aside from Ban who does not participate but does not attempt to stop his group either.

Animals[edit]

As she did in her other previous works already, Yumi Tamura placed strong emphasis on the deep connection of the protagonists with the nature surrounding them by having them interact with various animals who often play an important role in supporting the characters.

Aramaki's pack[edit]

Fubuki and Mitsuru-san paired up with others dogs and gave birth to many puppies. The whole dog population consists of almost hundred dogs by now. They're scattered in several smaller packs all over Honshu. Their appearances vary a lot. Still deeply attached to Aramaki although they don't live with him all the time anymore, they come when he calls for them and do various tasks for him like hunting, guarding duty, trailing tracks or searching for water and food sources. Their help was a great support for Aramaki and enabled him to survive in this dangerous new world all alone for 15 years.

Adult dogs[edit]
Fubuki

A male dog accompanying Aramaki ever since he was a puppy. He's the son of the nameless dog from Hokkaido who led Aramaki to safety after his other comrades perished. Fubuki also seems to be the male alpha dog of Aramaki's entire pack consisting of almost hundred dogs by now, scattered in several smaller packs all over Honshu. He looks very wolf-alike. Named after Aramaki's deceased friend Fubuki.

Mitsuru-san

A female dog accompanying Aramaki ever since she was a puppy. She's the daughter of the nameless dog from Hokkaido who led Aramaki to safety after his other comrades perished. Mitsuru-san also seems to be the female alpha dog of Aramaki's entire pack consisting of almost hundred dogs by now, scattered in several smaller packs all over Honshu. She looks very wolf-alike. Named after Aramaki's deceased friend Mitsuru.

Derek

An adult male dog from Aramaki's pack. Fubuki and Mitsuru-san paired with other dogs (as shown in a flash back), and each giving birth to a lot of puppies. They're almost a hundred dogs by now, scattered in several smaller packs all over Honshu. Derek leads the search team for Hana. He looks very wolf-alike. His special feature are two white circles around the eyes.

Juvenile dogs[edit]
Kuroda

Since he's often being bullied by the other dogs, Ayu adopts him as her own dog as per Aramaki's suggestion. Kuroda loves to tease his mistress and licks her all over whenever he gets the opportunity. His fur is completely black; he looks like a mixture between ibetan Terrier and Shih-poo.

Ball

He's hungry all the time and often trails off. But it isn't bad all the time because this way he was able to find Momota and deliver his call for help to Hana's group. Ball resembles a Laekenois, with scrubby light fur and black ears. He's very trusting even to strangers.

Puppies[edit]
Diamond (Dai)

A puppy from the latest litter of Fubuki and Mitsuru-san. The brother of Battery. Very curious and reckless. Looks like an Tibetan Terrier, dark coat, fair muzzle and legs. When he and his brother went astray on an adventure tour, he finds Hana and warns her of a reptile closing in on her.

Battery (Batsu)

A puppy from the latest litter of Fubuki and Mitsuru-san. The brother of Diamond. Very curious and reckless. Looks like an Maltese, with fair coat, curled tail and snapped off ears. When he and his brother went astray on an adventure tour, he is being chased by a large reptile, but Hana rescues him just in time.

Summer B's animals[edit]

Macadamia Nuts (Nuts)

A tabby cat who was Natsu's pet in the past, before she was sent to the future. She deeply misses him.

Peanuts

A baby flesh eating rabbit. Natsu wanted to keep it as her pet and Arashi suggested its name. However, it was killed by Mozu in order to prevent it from attracting the rest of its pack.

Carol

A llama-alike animal with a very keen sense for edible and dangerous food. She was given as a present from Izayoi to Team Summer B as they parted from Team Autumn. Ever since then, her delicious milk and her sharp instincts have been a great help to Team Summer B. She's also strong and can carry heavy luggage, even persons. Not even travelling on a ship does pose a problem to her.

Moron Birds

Arashi, Semimaru and Natsu at some point of the story discovered a flightless kind of birds and decided to take in some of them as a supply of eggs and bird meat. Because they're so trusting to humans, the cynical Semimaru decides to call them Moron Birds.

Ice Turtles

During their adventure in the ghost ship Fuji, Arashi picked up a pair of turtles which had been preserved in a hibernation state. Which kind of turtles they are, whether they're actually alive (and whether they're really a male and a female) is still unknown, though.

Team Spring's animals[edit]

Cheeky Foal

A still nameless, cheeky young foal which got attached to Hana and sticks close to her after its mother's death. White, curly fur, very beautiful and cute, but an extremely stubborn child, too.

Boar Family

A little family of boars, consisting of the mother and four baby boars. They befriend Hana and protect her as she just woke up from her fall into the whirlpool. But they have to painfully separate again because Chisa unknowingly killed and cooked one of the young boars, resulting in Hana accidentally eating her little friend.

Team Autumn's animals[edit]

Guri and Gura

Two llama-alike animals with a very keen sense for edible and dangerous food. They live with Team Autumn. The llamas' delicious milk and their sharp instincts have been a great help to Team Autumn. They are also strong and can carry and pull heavy luggage, even persons.

Gengorou's animals[edit]

Gengorou took care of many different animal species since he was part of the animal class during Summer A's time of education. He loved them deeply and built up a strong relationship especially to Tango and Aoba, but during Summer A's test he had to kill most of them with his own hands because they became dangerous to his comrades. It broke his heart.

Aoba

A tame large male brown bear which was reared by Gengorou ever since he was a cub. He was very trusting towards humans and got quite attached to Gengorou. But during Team Summer A's test he was probably deliberately infected with rabies and tossed out in the middle of the mountains. Pained and puzzled, he attacked Koruri's group and took away one of Unami's eyes. Unami shot him several times in return and Aoba died slowly, suffering great pains.

Tango

A tame large male tiger which was reared by Gengorou ever since he was a cub. He was very trusting towards humans and got quite attached to Gengorou. But during Team Summer A's test he was probably deliberately infected with rabies and tossed out in the middle of the mountains. Pained and puzzled, he attacked and killed several Summer A candidates. Gengorou took responsibility and strangled him to death.

Other animals[edit]

Saber-toothed tiger

A large saber-toothed tiger alike cat who killed several members of Team Winter. But after being killed by Aramaki, it turned out that the tiger also was just a mother who did her best to feed her cub. The cub ran away from Aramaki and was probably killed in the flame of the bushfire.

Ten-ten

A cute little dog owned by Maria. She brought it along with her into Ryugu Shelter, but Takashi took it away and quarantined it because he thought Ten-ten might be the "hidden carrier" of Acari X - a seemingly healthy parasite host showing no symptoms of illness, but infecting those around him. The dog was never seen again; he probably got disposed of. This entire thing caused Maria great grief. Ten-ten's fur was completely black; his appearance resembled a Shih-poo.

Setting[edit]

7 Seeds takes place an unknown number of years after the collision of a large meteorite with Earth. As a result of the impact, the climate of Japan has greatly changed from what the characters knew from the present day. In the Kansai region there are only two seasons, a dry season and a longer, heavier rainy season.[1] Takahiro of Winter group describes the winters in the northern island of Hokkaidō as being as mild as in Kanagawa Prefecture where he grew up.[2] In addition, sea levels have risen greatly: downtown Yokohama is completely underwater,[3] only the top hand of the statue in Nagasaki Peace Park is above the surface of the ocean.[4] The geography of Japan has changed as well: after an eruption of Mount Aso, Kyūshū has been split into two islands,[5] and the Kansai region is separated from central Honshū by a wide strait.[1] The series depicts a Japan in which, as a result of the new environment and mass extinctions, ecosystems have changed and several new species of animals and plants have evolved.

For example, on the island where Summer group B first lands, off the coast of Nagasaki Prefecture, Botan notes how few of the ecological niches are filled, including no birds or flying insects, and that the limited number of species are still radiating to fill empty niches.[6] In particular, a local rodent resembling a rabbit is in the process of speciation into herbivorous and ravenously carnivorous versions, which are still visually similar. Other dangers new to the characters include swarms of carnivorous white cockroaches and gigantic venus flytraps, sundews, and nepenthes. Species that are unchanged but were previously unknown in Japan include banana trees and crocodiles] Semimaru notes that neither on the island nor on the Kyūshū mainland do they see any ants, bees, or similar insects.[7]

In the Kansai region, Fall group domesticates flightless birds about the size of a chicken and sheep that have grown to resemble llamas, which can be ridden, milked and shorn for wool. Izayoi tells Natsu that a local wasp is deadly, killing with a single sting, and another species has a sting that sickens the victim for a day.[8] According to Akio, corn is the only crop from their seed cache that grows in the area's soils, but Fall group also cultivates a variety of tobacco with a narcotic effect when smoked.[1]

In the southern part of central Honshū, Natsu, Arashi, and Semimaru of Summer group B cross a desert with cactus scrub. Throughout the region they find remains of large reptiles that revive from estivation during the rainy season, which remind Natsu of velociraptors from Jurassic Park.[9] These "dinosaurs", as the characters call them, have grassland and woodland varieties, and during the rainy season are the dominant predator from the south coast to at least as far north as Tokyo.

On the island where the Spring group first lands, off the coast of the Kantō region, Hana notes that there are no vertebrates on land or in the sea, and Momotaro describes the ecology as similar to that of the Carboniferous Era.[10] On land, there are giant insects the characters call "boat beetles" and swarms of bees with stings that are painful but not deadly, which force the group to live on rafts off-shore. In the island's swamps, there are giant praying mantis and giant dragonflies. While at the island, the group lives off shellfish and shallow-water nautiluses, but see no bony fish. The characters find the climate changed as well, as it is too overcast to see the stars for the first two weeks after they are awake, even though it is spring, a season that in the present day is noted for clear weather.

On the mainland of the Kantō region, Spring group meets large aquatic lizards living among the submerged ruins of Yokohama, which hunt in groups. Nearby, in the ruins of central Tokyo, the party from Summer group B is attacked by a giant predatory fish, which Takahiro of Winter group identifies as descended from a deep-sea fish, the only kind of bony fishes to have survived.[11] They also meet a fungus-like growth Takahiro calls "blue mucus", which infects Hana's skin when she touches it. This growth goes dormant in the dry season, and Takahiro realizes it is intolerant to salt and uses it to cure her.[12]

In northern Honshū near Sendai, Natsu, Arashi and Semimaru of Summer group B find the first flowers they have seen during their journey over most of the length of Japan.[13]

In southern Hokkaidō, Winter group encounters grasslands populated by many mammals they do not know, including small-eared rodents, herds of unknown ruminants, and tigers with saber-teeth. They also meet wolves with the ability to project illusions normally used to help hunt.[2]

Development[edit]

In an author's note, Tamura says that 7 Seeds was inspired by news reports that near-Earth object (89959) 2002 NT7 might potentially collide with Earth.

The Four Seasons[edit]

A main topic of 7 Seeds naturally are the four seasons, since every team is named after one of them: Spring, Summer A/B, Autumn and Winter.

The team members were chosen into their teams based on which seasons their names matched best.

Almost every 7 Seeds chapter arc is named after one of the 24 solar terms consisting of the 72 pentads (Shichijūni kō). The Rainwater chapter, for example, completely consists of Shichijūni kō.
