Out of the blue, monsters usually living beneath the Earth’s surface began to attack the terrestrial world. They were called the Underground Hades Empire Infershia. The Ozu Siblings of Makito, Houka, Urara, Tsubasa, and Kai hear from their mother, Miyuki, that they are the Magicians of Justice to stand against the Infershia. The siblings are perplexed by such an unexpected event. However, without hesitation, Miyuki charges at the Infershia, and the Ozu Siblings are forced to come together to fight as one.

All across the universe, the Jark Matter empire has conquered everything they see. Meanwhile, the insurgent force called "Rebellion" is established and gathers nine ultimate saviors from across the galaxy who are chosen by the Kyu Globes, magical spheres with the power of the constellations.

Kenichi Yamada, a single, 35-year-old businessman, has spent the majority of his adult life playing every MMORPG to hit the market. Tired of the constant cycle of repetitive, newbie-centric gameplay, he is immediately drawn in by the promise of a new game that, on top of being never-ending, offers up a "Hell Mode"—a difficulty level that makes it nigh impossible to level up but also promises uncapped growth potential. Upon selecting the newly released Summoner class, Kenichi finds himself reborn as Allen, an infant in a serf family, with nothing but his wits and old memories to guide him.

During the war-torn feudal wars in Japan, the Awa clan faced certain extinction from a rival clan backed by demonic forces.

Their unnatural union bears fruit but when both are killed, the eight unborn pups are reincarnated as the eight Dog Warriors - The Hakkenden.

As they slowly find each other and come together as a group, these eight warriors, who represent the eight separate aspects of Bushido, engage in bloody battles with demonic entities and evil samurai in a final attempt to redeem their clan!
