Slam Dunk

Slam Dunk centers around Hanamichi Sakuragi, who starts as a delinquent outcast, becoming the leader of a gang. Hanamichi, being very unpopular with girls, has been rejected by them fifty times. Yet, he finds out that Haruko Akagi is the girl of his dreams, and is happy when she's not scared of him like all the other girls he has asked out.
Haruko Akagi, who recognizes Hanamichi's athleticism, introduces him to the Shohoku basketball team. Hanamichi was reluctant to join the team at first because he had no previous background in any sports and thought that basketball was a game for losers (also because the fiftieth girl rejected him for a basketball player). Sakuragi, despite his immaturity and hot temper, proves to be a natural athlete with potential and joins the team in order to impress Haruko and prove that he is worthy of her. Later on, Sakuragi realizes that his love for the sport equals that of his crush on Haruko. Kaede Rukawa — Sakuragi's bitter rival (both on the basketball court and love, even when Rukawa doesn't acknowledge Haruko's crush on him), the star rookie and a "girl magnet" - joins the team at the same time. Hisashi Mitsui, an ex-junior high school MVP, and Ryota Miyagi, a short but fast player, both also rejoin the team and together these four struggle to complete team captain Takenori Akagi's dream of making Shohoku the national champion. Together, these misfits gain publicity and the once little known Shohoku basketball team becomes an all-star contender in Japan.

Trinity Blood

When Earth's population drastically increased, humanity, led by the United Nations, attempted to colonize Mars. During the colonization, they discovered two alien technologies: the Bacillus virus and the Crusnik nanomachines. The colonists injected the Bacillus in their bodies which transformed them into "Methuselahs." They installed the Crusnik in the bodies of four test tube babies: Seth, Cain, Abel and Lilith whose enhanced bodies were the only ones able to survive the procedure.
Continuing wars on Earth eventually led to "Armageddon," the apocalyptic event that happened 900 years before the start of the story, and the colonists returned to Earth to help with rebuilding. However, when the colonists returned to Earth, a war broke out between the Methuselahs and the humans who had remained on Earth. Abel, Cain, and Seth took the Methuselah's side—while Lilith supported the Vatican, which guarded humanity. During the war, Cain went insane and killed Lilith. In grief, Abel took her body to the Vatican where she was buried. Abel remained at her side, weeping for her, for 900 years.
At the start of the story, the vampiric Methuselahs, still a major political and military force, continue to wage war on the "Terrans," as they call the human inhabitants of Earth. The Roman Catholic Church is a major military power determined to protect humans from the Methuselahs, with its seat of power based in the Vatican. The Methuselahs have their capital in Byzantium, which is surrounded by a field of particles to filter out UV radiation, protecting the Methuselah population.
Both groups use "lost technologies," such as airships, missiles, and computers, to engage in a cold war with one another. A third great power, Albion also plays a role in the war with its superior arsenal of lost technology and weapons and higher level of manufacturing ability versus the Vatican. The independent monarchy of Albion is a primarily human country, however the secret of their expertise in lost technology is found in the Ghetto, an underground city of enslaved Methuselah. It is these Methuselah who operate and manufacture the lost technology, but with the death of the Albion Queen, some of the enslaved vampires begin a rebellion for the freedom of all of the Ghetto residents.
