Tamura, Yumi

Natsu Iwashimizu's last memory of her family is eating her favorite meals with them. Unfortunately, she wakes up from her dream only to find herself in a sinking ship, being rescued by three strangers: Arashi Aota, whose kind-hearted personality does not match his quick temper; Semimaru Asai, who enjoys ridiculing Natsu's meek nature; and Botan Saotome, a skillful woman seemingly aware of their situation. 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.

"Geass" is a supernatural ability bestowed upon people who are worthy of its use. Its exact effect depends on its user's desires, but those who command it wield devastating power. 

In the far away land of Area 11, formerly known as Japan, the astute 17-year-old student Lelouch Lamperouge is granted his own Geass by the mysterious woman C.C., which gives him the absolute obedience of those it is used upon. With this, Lelouch vows to destroy the only world superpower—the Holy Britannian Empire—under the guise of the revolutionary freedom-fighter Zero, to exact vengeance on those who ruined him and his family.

In the far future, two young military leaders rise above their peers. The invincible genius Reinhard von Lohengramm is matched only by the unbeatable magician Yang Wen-li; though the two share a profound respect for each other, they meet on the battlefield not as comrades but as bitter adversaries. Commanding thousands of warships and millions of soldiers, they lead giant space fleets into battle on behalf of the two interstellar states that have wrested for control of the Milky Way for over a century and a half. 

The Galactic Empire, an absolute monarchy ruled by Kaiser Friedrich von Goldenbaum IV and an entrenched nobility, seeks to suppress the rebels daring to oppose the inviolable crown. The Free Planets Alliance, a representative democracy led by a corrupt High Council, degenerates as its elected leaders⁠ use war and conflict as a way to win popular support. Reinhard is a minor noble who became a High Admiral through his strategic brilliance and his sister's position as the favored concubine of the Kaiser, while Yang is an avid historian and reluctant commodore hailed as a hero despite only using his tactical prowess to navigate around his leaders' incompetence. On opposite sides of the galaxy, the two men have wildly different visions for the future: Reinhard dreams of uniting mankind under his iron fist, while Yang wants only to carve a path to lasting peace. As the war rages on, Reinhard and Yang each strive for their ideals and secure their place among the stars as the leaders of a new era of galactic heroes.
