One afternoon, while taking a break from cleaning duty, he stumbles across a strange message that goads him to conquer a girl. On a whim, he accepts, and his consent summons a girl named Elucia "Elsie" de Lute Ima, a denizen of hell tasked with capturing runaway spirits that have festered in girls' hearts. Keima is shocked and tries to escape, but Elsie tells him that failure to fulfill the newly formed contract will result in the termination of his life!

Tasked with capturing the runaway spirits, Keima uses his expertise and knowledge of dating sims to obtain the hearts of girls in real life.

The story is set in a distant future where Japan is divided into feudal territories and conquered by other countries. There is a floating city named Musashi that is composed of eight ships in the skies. A war that will determine the fate of the world will be fought by students on the Musashi.

In the far future, humans abandon the devastated Earth and move to the upper world "Tenjou." But Tenjou and the law of causation collapse due to a war and humans are forced to return to the Earth, which has turned into an inhabitable planet except for Shinshuu area in the Far East. Shinshuu is too small to accommodate all the humans, so they duplicate the area and create "Juusou Sekai" in a parallel world. In order to rebuild Tenjou and the law of causation, the returned humans start reproduction of the history from B.C. 10,000. When the reproduction proceeds to A.D. 1413, a war breaks out in Shinshuu and Juusou Sekai falls onto the original world. The humans living in Juusou Sekai lose their land and invade the original world. People in Shinshuu surrender and the land is divided by the invaders from Juusou Sekai. They try to resume the history reproduction from A.D.1457, but the update of the history terminates in A.D.1648. A rumor of apocalypse begins to spread the world.

Kusuo Saiki is not your typical high schooler—behind his glasses, pink hair, and antenna-like appendages exists a being of unfathomable psychic power. Telekinesis, teleportation, and astral projection might sound exciting to the average person, but from Saiki's viewpoint, they are nothing but an annoyance. Psychic powers are unnecessary—this is all that Saiki has believed since he was a kid.

As a secret esper with the sole dream of living an ordinary life, Saiki tries to use his psychic abilities to stay out of the public's gaze. However, having to clean up after his odd classmates and their antics, all the while keeping his psychic powers a secret, makes it rather difficult to achieve the peaceful life he desires.

High school teacher Nozomu Itoshiki has been waiting for a chance to end his life. He has grown averse to the very idea of toiling every day to make an ordinary living, and he makes no attempt to conceal his crushing despair. Sadly, he is almost always dragged into the bizarre—and sometimes outright suspicious—problems of his quirky students. Every time he gets a little closer to kicking the bucket, he finds himself in an absurd situation, trying to save his students from the same rabbit hole of misery that haunts him.

Despite his ever-present existential crisis, Itoshiki attempts to find a new normal in the silliness of his daily adventures—all the while chasing the sweet demise that eludes him.

Ishiyama High—land of the delinquents. No matter how tough you think you are, you don't mess with an Ishi-high student. One of the most infamous students is first year Tatsumi Oga, called "Demon King" by those he's defeated. 

One day, while Oga is finishing off a gang that attacked him, he stumbles upon an infant. In a rare moment of kindness, Oga tries to care for the baby. As a result, the child becomes overly attached to him. In a panic, he brings the baby to his best friend Takayuki Furuichi's house. While there, they are attacked by Hildegard, a demon maid who says the baby is actually Kaiser de Emperana Beelzebub IV. She also reveals that he was sent here to destroy humanity, on a whim of his father Beelzebub III, Great Demon Lord of the Demon World. After failing to remove Baby Beel from Oga, she declares that he must raise him, as moving more than 15 meters away will result in instant death for Oga.

With his delinquent past and unfriendly nature, Oga must deal with the burden of raising a demon baby. Beezelbub follows his story through encounters with demons and dangerous classmates, all while being an unorthodox role model and carer for the young Baby Beel.
