Toriyama, Akira

Bulma, a headstrong 16-year-old girl, is on a quest to find the mythical Dragon Balls—seven scattered magic orbs that grant the finder a single wish. She has but one desire in mind: a perfect boyfriend. On her journey, Bulma stumbles upon Gokuu Son, a powerful orphan who has only ever known one human besides her. Gokuu possesses one of the Dragon Balls, it being a memento from his late grandfather. In exchange for it, Bulma invites Gokuu to be a companion in her travels.

By Bulma's side, Gokuu discovers a world completely alien to him. Powerful enemies embark on their own pursuits of the Dragon Balls, pushing Gokuu beyond his limits in order to protect Bulma and their growing circle of allies. However, Gokuu has secrets unbeknownst to even himself; the incredible strength within him stems from a mysterious source, one that threatens the many people he grows to hold dear.

As his prowess in martial arts flourishes, Gokuu attracts stronger opponents whose villainous plans could collapse beneath his might. He undertakes the endless venture of combat training to defend his loved ones and the fate of the planet itself.

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.

DRAGON QUEST -ダイの大冒険-

Watanabe, Michiaki

Pandora's Box led a cursed existence. Through the curiosity of a woman, evil was unleashed and very nearly covered the world in darkness. Miraculously, humanity managed to seal Maou Kestra back into the box, but only with immense sacrifices. Even without their lord, the demons are still a formidable force that has only grown stronger with time, locked in the abandoned capital of the North, Hameln. Fifteen years have passed since that fateful battle...

Meet Hamel, a travelling minstrel who is so self-centered that he'd sooner cook his guardian crow (and family friend), Oboe, than go hungry for even a minute. Welcome to the world of music and hilarious insanity that is the Violinist of Hameln. Watch as Hamel takes cheap shots at his opponents and bashes pigeons with his giant violin and turns them into dinner.

How WILL the world be saved from Maou Kestra with a hero such as this?

Hameln no Violin-hiki

ハーメルンのバイオリン弾き

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.

Outlanders

アウトランダーズ

Tezuka, Osamu

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.

Young sorceress Lina Inverse and her dim-witted sidekick Gourry Gabriev travel through a somewhat medieval setting, doing good and fighting evil. Well, by "doing good and fighting evil" I mean "stealing from corrupt rich people and blowing things up".

Ozanari Dungeon

おざなりダンジョン

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.
