A group of ninja is planning to revive a powerful demon, and once its spirit is reunited with its body, the world will be destroyed. The only way to prevent this from happening is for Shion, a shrine maiden, to seal it away for good. Naruto Uzumaki is tasked to guard her, but one thing stops Shion from accepting his help: she also has the ability to predict death—and she has foreseen his demise approaching soon. In order to escape his fate, Naruto must stay away from Shion; however, undeterred, he chooses to challenge the prophecy in order to protect Shion and the world.

The demon Jashin-chan has been summoned to Earth by Yurine Hanazono, a girl with a knack for the occult. Unfortunately, Yurine does not actually know how to send Jashin-chan back to Hell. Now stuck on Earth, she must live at Yurine's apartment as her familiar. The only way for Jashin-chan to return would be to kill her summoner, but this is easier said than done for the incompetent demon. Since Jashin-chan is immortal and can regenerate her body, Yurine does not hold back in attacking her with a range of weapons, punishing her in gruesome manners for her evil schemes. Jashin-chan is also often visited by her demon friends: the kindhearted Gorgon Medusa and the energetic minotaur Minosu, who seem much more well-behaved in contrast, and disapprove of her plans to kill Yurine. Jashin-chan Dropkick is a comedy focusing on these two reluctant roommates and their bizarre antics as they get by with their cat-and-mouse relationship.

Death does not have to be the end; one can live again, but only through beating the game posed by the black ball called Gantz. On his way home to celebrate his younger brother's birthday, brave and kind-hearted student named Masaru Katou is stabbed to death. He awakes in a small room with a cityscape view in the heart of Tokyo—and he is not alone. To his surprise, it is not the afterlife, but the waiting room for a high stakes game with their lives on the line. Before he has the chance to process the situation, Masaru is handed a gun and teleported into the center of Osaka to carry out one simple task: eliminate any alien on sight. Accompanied by the aged Yoshikazu Suzuki, the stunning idol Reika Shimohira, and the cold but experienced Jouichirou Nishi, Masaru must overcome his fears in order to survive the game and return home to his waiting brother.
