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.

Togashi, Yoshihiro

Fourteen-year-old thug Yuusuke Urameshi spends his days skipping school and causing trouble for the adults in his life. Yuusuke regularly engages in street brawls against rival Kazuma Kuwabara and ridicules his childhood friend Keiko Yukimura. Filled with self-loathing and the burden of an alcoholic mother, Yuusuke sacrifices it all in a split-second decision—he tackles a small child out of the way of an oncoming car, losing his life in the process.

Spirit guide Botan intervenes, allowing Yuusuke to see how the people in his life react to his death; he is moved by the emotional ruin his loss causes his mother, Keiko, and even Kuwabara. Additionally, due to his death's heroic nature, he receives an opportunity to return to life from the Spirit World ruler's son, Koenma.

Koenma hires Yuusuke as a "Spirit Detective" and tasks him with solving a series of increasingly challenging paranormal mysteries. Battling and befriending demons such as the beautiful Kurama and hostile Hiei, Yuusuke further develops and utilizes his skills as a fighter. But as dark forces move in the Underworld, Yuusuke struggles alongside his companions to defend everything he took for granted.

After the cruel lord Daigo Kagemitsu sells his newborn son's body parts to 48 demons in exchange for power, he casts what remains down a river and quickly forgets about his son, soon establishing a mighty kingdom. Little does Daigo know that his child survives, possessing advanced spiritual senses that allow him to navigate the world without eyes, ears, limbs, or even a voice.

A brilliant doctor rescues the son and raises him as his own, naming him Hyakkimaru and fitting him with advanced prosthetics that make it possible for him to move and fight. However, tragedy strikes when Hyakkimaru turns out to be a beacon that brings demons into the doctor's home, and the doctor eventually has to send Hyakkimaru out into the world.

Amid his travels, Hyakkimaru learns that slaying demons allow him to recover his missing parts and seeks to kill enough to make himself whole. He soon encounters Dororo—a boy claiming to be the world's greatest thief—who joins Hyakkimaru against his will in hopes of one day obtaining his sword. Together, the duo travels through a countryside infested with both demons and brutal men, who might prove to be worse.

Dororo

どろろ

Ishikawa, Ken

The first Getter Robo series chronologically published 15 years before the rest of the manga. Getter Robo pioneered the idea of the combining and transforming robot.

Millions of years ago, the dinosaurs were driven deep underground due to the sudden arrival of "Getter Rays" on Earth. After evolving into sentient beings, they grew bitter and vengeful at the humans who replaced them on the surface and began plotting their attack on humanity.

Fighting against them is Getter Robo, a machine built by Professor Saotome which uses the mysterious Getter Rays as its power source. Piloting it are three strong-willed young men—the violent martial artist Nagare Ryoma, the psychopathic yet highly intelligent revolutionary Jin Hayato, and the hot-blooded judo master Tomoe Musashi. Each controls one of three specially designed combat jets which can be combined together in different forms to form three different kinds of giant robots: the flying, axe-wielding Getter-1, the quick, drill-wielding Getter-2, and the tough, tank-like Getter-3.
