When an asteroid threatening to wipe away planet Earth appeared, humanity's brightest minds came together to develop the "Moon Shield" plan. To protect the planet, rockets would blast the asteroid apart, and the Moon would shield the Earth from the remaining debris. However, the plan failed by the smallest of margins: one sliver made it past the shield and crashed into Earth. There to witness the end of the world was Moon Yoo, a researcher left stranded on the Moon.

Unable to find the courage to end his life, Moon decides to make the most of what he has as the last man alive. With supplies to last a lifetime and all the time in the world, Moon decides to explore the vast lunar base, unaware of the many secrets that lie in wait to be discovered—and the fact that he may not be as alone as he initially thought.

Koyama, Chuuya

"A big brother must always stay ahead of his younger brother. That is my responsibility as the older sibling"—these are the words that have always motivated Mutta Nanba to try his best when it came to his younger brother, Hibito. So naturally, in the summer of 2006 when the Nanba brothers witness something strange in the night sky, Hibito declared that he would become an astronaut and travel to the Moon, while Mutta countered with the affirmation that he would go to Mars. That was the promise they made to each other.

Now in 2025, while Hibito is working with NASA and preparing to become the first Japanese to land on the moon, Mutta has been fired from his job in an automotive development company. Having difficulty finding another job, Mutta is given a lifetime opportunity when he receives a letter from JAXA—the Japan Aerospace Exploration Agency—telling him that he has been accepted to participate in the next astronaut selection. As if fate has given him a chance to fulfill the promise he made all those years ago, Mutta undertakes the difficult challenge of going to space.

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.

Legend of the Galactic Heroes

銀河英雄伝説

Nightow, Yasuhiro

Much of the damage attributed to "Vash" is caused by the activities of bounty hunters who are after the 60,000,000,000$$ (sixty billion "double dollars") reward on Vash's head for the destruction of a city called July. Vash does not clearly remember the destruction of July, and only wants "love and peace", as he puts it; though he is a gunfighter of inhuman skill, he uses his weapons only to save lives wherever he can.

As the series progresses, more is gradually learned about Vash's mysterious history and the history of the human civilization on Gunsmoke, the desert planet the series is set on. The series is often humorous in tone, but at the same time it involves very serious character development and especially in later episodes it becomes quite emotionally intense. Vash is occasionally joined by a priest, Nicholas D. Wolfwood, who is almost as good a gunfighter as Vash himself, and later is targeted by a band of assassins known as the Gung-Ho Guns for reasons which are mysterious at first.

Trigun evolves into a very serious discussion of the nature of morality, posing questions such as: What is the nature of morality? Can we judge different moral codes? If a person is forced to betray their moral code, does that betrayal invalidate that moral code, and can the person still try to live up to that moral code? Can the person find redemption from their wrongs, and if so, how?

Itou, Noizi

As the students of Class 1-5 introduce themselves at the beginning of their high school careers, the cynical but otherwise fairly ordinary boy known as Kyon sits down, having just finished his piece. However, when the girl sitting behind him stands up to give her speech, the words she utters dumbfound the entire class. Proclaiming that she has no interest in ordinary humans and is in search of the supernatural, Haruhi Suzumiya makes her unforgettable debut.

Doubting Haruhi's sincerity, Kyon lets his curiosity get the better of him and attempts to befriend her in spite of his classmates' warnings. Unfortunately, as the eccentric girl slowly opens up to him, Kyon realizes she is dead serious. Moreover, a conversation between the two sparks a dangerous idea in Haruhi's mind: since she is bored with the mundanity of the school's clubs, she should just create her own. With this, the SOS Brigade is born, and Kyon is quickly dragged into a life of absurdity.

Taking over the Literary Club's room, Haruhi soon enlists three new members into her organization: the stoic Yuki Nagato, the timid Mikuru Asahina, and the supposedly mysterious transfer student Itsuki Koizumi. Having thrown together this group of students, Haruhi drags the squad around on adventures in search of the exciting and supernatural, much to Kyon's chagrin. However, he soon discovers that there is more to the new recruits than meets the eye, and that which Haruhi wishes for may be much closer than she realizes.
