Full Metal Panic!

フルメタル・パニック!

Tezuka, Osamu

From time immemorial to the age of space colonization, there is one legend that has stayed unchanged in every history book—the tale of the immortal bird Phoenix. A being whose blood is said to grant eternal life or wisdom, the radiant figure ensures the continuation of sentient life in the universe as it oversees human civilizations and their development.

Yet, mankind remains a slave to its habits; from happiness and sorrow, to wrath and love, a myriad of emotions continue to play an integral part of human life. Simultaneously, time and time again, certain beliefs and agendas persist over the centuries to disturb the fragile equilibrium of the world's preordained nature and principles. It appears that fate, with its dynamic variables, can manifest itself in many ways—and oftentimes exhibits a bizarre sense of humor.

Kareno, Akira

Willem Kmetsch wakes up from his icy slumber as the last surviving Emnetwiht, a race of humans that populated the planet’s surface until they met their untimely demise five centuries ago at the hands of "Beasts." Currently, he lives among the hundred odd floating islands that make up civilization—otherwise inhabited by various other species, all of whom possess distinct animal-like features such as horns, fangs, wings, and scales. Because he lacks any such feature, Willem is referred to as a "markless."
 
One day, Willem encounters another markless named Ctholly Nota Seniorious. He thinks nothing of the meeting, and continues to spend his days working odd jobs until he runs into her again, this time after accepting a military posting.  Willem soon learns that the group of bubbly young Leprechauns he is tasked to look after are pivotal in the ongoing battle against the Beasts. These girls, who have had little exposure outside a world where they are treated as weapons, are willing to die if it means defeating the Beasts.

Determined to nurture a life of normalcy for them, Willem soon becomes a father figure to the girls. Just like how he once went off to battle, he must now come to terms with watching these children go off to war.

Following the four's successful escape, they sail to a deserted island.

Unbeknownst to them, the mysterious island is Japan. After a meteorite landed on Earth, humanity was wiped out and the environment changed drastically. To repopulate the country, the government initiated the "7 Seeds" project, consisting of five groups—Spring, Summer A, Summer B, Autumn, and Winter—each with seven young healthy individuals and a guide. Natsu and the others were put into team Summer B, whose members are considered failures by society.

To get more supplies, the group must find one of the seven shelters built by the government. In a hostile, unfamiliar world with no loved ones to depend on, the quartet must learn to cooperate with each other to ensure their survival.
