Samura, Hiroaki

Manji is an infamous swordsman in feudal Japan who is known as the "Hundred Man Killer," as he has killed one hundred innocent men. However, there is something far more frightening than his ominous reputation: the fact that he is immortal. This is the handiwork of eight-hundred-year-old nun Yaobikuni, who placed bloodworms capable of healing almost any wound in Manji's body. 

To atone for his crimes, Manji resolves to kill one thousand evil men. Yaobikuni agrees to this proposal, saying that if he succeeds, she will undo his curse of immortality. Soon after this promise, Manji meets Rin Asano, a 16-year-old girl who requests Manji's assistance in killing those who slaughtered her parents.

Initially reluctant, Manji refuses Rin's desperate plea. However, owing to her evident lack of strength, Manji changes his mind and agrees to protect Rin for four years. With this partnership set in stone, the two embark on a perilous journey of bloodshed, vengeance, and redemption, each to fulfill their own life's cause.

In the Meiji Era of Japan, legend has it that the "Orochi"—an evil giant snake spirit—returns every 300 years to wreak havoc. "Yamainu," an elite fighting force, is assembled to subjugate the Orochi upon its reappearance. Presently, the squad has become involved with a secret government department conducting human experimentation using Orochi cells. This pits Yamainu leader Sousei Abeno against brothers Soramaru and Chuutarou Kumou, who stumble upon several dying escapees of the experiments.

Soramaru encounters Ageha, a criminal doctor allied with Tora, a test subject who massacred cell project researchers using abilities granted by compatible Orochi cells. Despite acknowledging their crimes, Soramaru still decides to side with the two fugitives due to his strong opposition to the exploitation of Orochi cells. With Sousei and Soramaru divided over the ethics of creating novel drugs from the essence of their immortal enemy, the only way to settle this matter may be a fight—however, Soramaru has yet to win once against Yamainu's captain.

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.

In 16th-century Japan, Shinmen Takezou is a wild, rough young man in both his appearance and his actions. His aggressive nature has won him the collective reproach and fear of his village, leading him and his best friend, Matahachi Honiden, to run away in search of something grander than provincial life. The pair enlist in the Toyotomi army, yearning for glory—but when the Toyotomi suffer a crushing defeat at the hands of the Tokugawa Clan at the Battle of Sekigahara, the friends barely make it out alive.

After the two are separated, Shinmen returns home on a self-appointed mission to notify the Hon'iden family of Matahachi's survival. He instead finds himself a wanted criminal, framed for his friend's supposed murder based on his history of violence. Upon being captured, he is strung up on a tree and left to die. An itinerant monk, the distinguished Takuan Soho, takes pity on the "devil child," secretly freeing Shinmen and christening him with a new name to avoid pursuit by the authorities: Musashi Miyamoto.

Vagabond is the fictitious retelling of the life of one of Japan's most renowned swordsmen, the "Sword Saint" Musashi Miyamoto—his rise from a swordsman with no desire other than to become "Invincible Under the Heavens" to an enlightened warrior who slowly learns of the importance of close friends, self-reflection, and life itself.
