Devilman

デビルマン

Matsumoto, Leiji

Tetsurou Hoshino is a young street urchin who desperately wants to replace his human body with an android body, which would grant him immortality and the social freedom the androids have. Normally this is incredibly expensive but it has long been rumored that if you board the Galaxy Express headed for the Andromeda Galaxy, at the end of the line is a planet where they are given out for free.
After seeing his mother murdered by an Android Count, he has no reason to remain on his home planet and nothing to hold him back. Now, not only seeking the android body of his dreams but also a way to avenge his loss, he begins to search for a way to board the train alone.

Then he meets Maetel, a mysterious woman who offers him a ticket aboard the train if he will be her companion for the journey.
Their journey will take them to planet after planet, each strange and new, and each stop along the way being an opportunity for Tetsurou to reflect on being human, human actions, and the prospect of immortality. During their travels Tetsurou and Maetel meet, amongst others, Emeraldas and Harlock.

銀河鉄道999

Takahashi, Kazuki

High school student Yuugi Mutou spends his days being bullied between classes and his nights playing board games and solving puzzles in his bedroom. Yuugi's penchant for gameplay comes from his grandfather, whose game shop also serves as a house for the two.

One night, Yuugi manages to solve the Millennium Puzzle, a seemingly impossible challenge that awakens his inner darkness and converts it into an alternate persona: Yami Yuugi. Transforming into the more bold and dangerous persona against his will in moments of great distress, Yuugi begins to moonlight as a vengeful vigilante, challenging bullies and evil-doers to risky games where failure results in fates worse than death.

Yuugi and his alter ego befriend some of the very students who once bullied him, forming unbreakable companionships with them. But the group must contend with villains far deadlier than the high school punks they originally rallied against, enemies who use games for nefarious purposes and threaten Yuugi and his friends' very lives.

Yu-Gi-Oh!

遊☆戯☆王

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.

Chiba, Katsuhiko

The novelization contains four sections:

The first section covers Yuugi solving the Millennium Puzzle.

The second section covers Yuugi's first encounter with Seto Kaiba from the manga.

The third section covers the second encounter with Kaiba in Kaiba Land. It omits many areas that don't deal with the card game.

The fourth section is an original story, occurring only in the novel. Two weeks after Yuugi's battle with Kaiba in Kaiba Land, Yuugi gets a call from Kaiba, who tells him to meet for a Duel at the top floor of the KaibaCorp. Yuugi accepts, and when the duel begins, they use a special variation called the "Bingo Rule," which prevents the used of a specific card in each player's deck. Kaiba seems to be himself, but plays a different trump card, the "Automatic Giant."

Mokuba stumbles in on them, and tells Yuugi that Kaiba has not yet awoken from his catatonic state. It turns out that the Kaiba that Yuugi is playing against is a Cyber Kaiba, controlled by the KaibaCorp computer, and using all of Kaiba's memories.

Yuugi defeats the "Automatic Giant" and Kaiba with a card called "The Unknown Egg."

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.

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.

Majin Sai wanted to use this technique to further “Chiguruma Tou’s” cause and make their warriors invincible. Tani No Majyu resisted handing Majin Sai the secrets to this technique believing that in the wrong hands, this technique could pose a monumental threat to Japan. Majin Sai sent one of his “Youkai Ninjas” (Supernatural Ninjas) to steal the secrets of this technique. In the process Tani No Majyu was killed but not before he had shown Hayate the secrets of this process.
