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.

Nagai, Go

Soft-hearted Akira Fudou has always been somewhat of a pushover. When he reunites with his childhood friend, Ryou Asuka, in a fateful encounter, Ryou reveals to him the terrifying reality of his father's research: demons exist and are planning to claim possession of the earth once again.

Eager to help his friend save humanity, Akira agrees to attend Black Sabbath, a party filled with depravity and corruption, to attempt to merge with a demon. A near-death encounter causes him to unify with Amon, a demon feared amongst even his own kind. Together they form Devilman, a combination of Amon's strength and Akira's pure heart.

After uniting with Amon, Akira begins to fight against the demons with his newfound power, desperate to stop the downfall of all human civilization.

Yuuki, Masami

In the near future, large mecha called Labors are made to assist in various reconstruction projects in major countries around the world that are being threatened by global warming. In Japan, the government has enacted Project Babylon in order to conduct land reclamation. Labors are also being pressed into police and military service aside from civilian use.

However, terrorists are now attempting to use labors to make themselves heard, as well as common criminals, thugs and guerrillas. The National Police Agency established the Special Vehicles Division, an all-labor task force to combat the potential use of labors for criminal/terrorist activities.

Matsumoto, Leiji

In the future, humanity has achieved a vast starfaring civilization, but is slowly and steadily succumbing to ennui or despair, often due to defeat and subjugation by a foreign invader. Rising against the general apathy, Herlock denies defeat and leads an outlaw crew aboard his starship Arcadia to undertake daring raids against Earth's oppressors. Their primary oppressors are the Mazone, a race of organic plant-based alien women who explored Earth in the mythic past and are now back to reclaim it.

Adachi, Mitsuru

The story is set in a place very similar in appearance to Earth in the Edo period. However, Adachi (the mangaka) regularly reminds the reader all throughout the series that the setting is another planet in the distant future which just happens to look like Earth.

After the death of his mother, Shichimi sets out to join his step-brothers and -sister who live together in Karakuri Tenement, a place provided by the father they have never met. He finds out that each of them had different mothers (all of whom have died), but were fathered by the same man. Not long after Shichimi's arrival, the siblings decide to journey to visit the graves of each of their mothers. On this journey, they encounter many dangers.

Silent Möbius

サイレントメビウス

Hijiri, Yuki

At first glance the story is simply about Locke. He has no family name; when asked "Locke what?" he replies "Just Locke." His genesis is before the "Cosmic Year" calendar used in the story. Although there are rumors that the author has an origin in mind for Locke, it is still a mystery to readers as well as to the other characters in the story. All of the stories deal either directly with Locke or with actions only slightly removed from him. The primary plot deals with Locke's involvement in struggles against evil of one sort or another—either human or quasi-supernatural. Frequently Locke is drawn into events that are happening around him. Either he stumbles onto a situation that his heart will not let him ignore, or one of the other players begs him to join their cause. Sometimes he relents and joins their cause; sometimes he ends up opposing them.

As the story slowly grows around the reader (and there is a lot of story!) he finds that it is a chronology of human history in the future. Locke is the medium through which we see humanity as it evolves, travels, discovers, explores, colonizes, conquers, fights, and destroys. He is the eye on humanity. He is also the will to do right.
