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

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.

デビルマン

Kanzaka, Hajime

Araizumi, Rui

After pilfering as many valuables from a band of thieves as she can carry, Lina Inverse—self-proclaimed beauty and genius sorceress—departs with the gift of a fireball into the heart of her unwitting patrons’ campsite and continues on to Atlas City with dollar signs in her eyes. Before she can get very far, a horde of the surviving bandits ambushes Lina with vengeance on their minds. But sooner than she can put these one-dimensional goons out of their misery, a gallant wandering mercenary enters the scene, mistaking Lina for a damsel in distress.

Lina gladly plays the role and lets the swordsman, Gourry Gabriev, do all the work for her. Soon enough, however, she comes to regret her decision, as Gourry insists upon his honor on escorting Lina the rest of the way. The thought sends shivers down her spine, but when the original owners of her stolen goods come to take them back, Gourry proves more valuable than anything of theirs. Figuring out that whichever item they seek is being tracked via magic and that some big names are attached to what is quickly becoming quite the scandal, Lina realizes that something far more precious than money has fallen into her hands.

スレイヤーズ

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?
