Rinne Rokudou has bigger problems than going to school—namely, helping spirits pass over to the next life. Because of this responsibility, he often finds himself short on money and struggles to buy his necessities: food, clothes, and exorcism tools. Sakura Mamiya has been able to see ghosts since she was little. She hoped she would outgrow it, but even after starting high school, nothing has changed. To make matters worse, the first time her ever-absent classmate, Rinne, shows up for school, only Sakura can see him. She assumes, as anyone would, that he is a ghost. However, to Sakura's surprise, Rinne proceeds to attend school like normal the next day. Kyoukai no Rinne chronicles Sakura's journey as she learns of Rinne's true nature and the existence of a hidden supernatural world.

Vampires are known to have many weaknesses that balance out their incredible power, but the vampire lord Draluc happens to be weak to pretty much anything. The vampire hunter Ronald receives a job to infiltrate the castle of the so-called Invincible Progenitor and rescue a woman's son from the monster within. But upon arriving, he is dumbfounded to discover that the vampire quickly turns to ash by something as trivial as a clap of his hands! Moreover, the child he was sent to save had merely wandered in to play the vampire lord's video games while he slept! In a disastrous turn of events, Draluc's castle is destroyed, and the fragile vampire decides to move in with the hunter who has only just defeated him. Ronald, Draluc, and the vampire's pet armadillo John form quite the eccentric team as they are forced to work together while fending off Ronald's violent editor, the lesser vampires plaguing the city, and even their fellow vampire hunters.

Shou and his friend, Tetsurou, stumble upon a strange orb-like mechanism, the Guyver Unit, in the woods. It physically bonds with Shou and turns him into the alien soldier, Guyver. His mission is to protect the Guyver Unit from the Japanese corporation known as Chronos. They are after it and two other units just like it. To retrieve the object, they send out vicious monsters known as Zoanoids. So no one is safe in Shou's life; not even himself.
