Beelzebub - Part 1

Oga Tatsumi is a crazy-strong, ruthless high school delinquent who's nicknamed the "Rampaging Ogre". One day, while dunking some punk, he rescues a big guy who comes ~floating~ down the river.

Oga has been chosen to be the parent of Beelzebub, the son of the Great Demon Lord.

Oga loses the powdered milk that Hilda prepared for him, and instead buys a bunch of "Yogurty" from a vending machine for Beel.

When Oga wakes up one morning, he's floating in a great pool of water... However it is actually Baby Beel's pee, as it is "urination season" right now in the Demon World.

On the back of Oga's fist a mark appears that is proof of his contract with the son of the Demon Lord, Beelzebub... The Zebul Spell.

A - Hilda brought back a bunch of toys from the Demon World for Baby Beel. When Oga and Hilda were assemble one, a horrible accident occurs! B - The Zebul Spell expands when one does evil.

It is when you first join the community of mothers who bring their young children to the park. That day, Oga took Baby Beel to the park for his nerve-wracking debut...

TKKH, who holds the deep confidence of all the women, has returned from subjugating all the Ladies of North Kanto! Hearing the rumors, Furuichi drags Oga along in trying to get a glimpse of her.

Hilda hears about Kunieda Aoi from Oga and wants to find out more. She goes in search of her to test her skills.

A cat follows Oga home one day. Baby Beel challenges the cat for Oga's attention. This is the start of a friendship between 1 baby and 1 kitty.

Himekawa lives by the motto, "there's nothing that money can't control."

Oga's family is seriously worried about Baby Beel's night crying, as it's causing everyone in the entire town to lose sleep.

It's the Ability Assessment tests for Ishiyama High, the den of delinquents. Oga tries studying for the test, for once.

Kanzaki is thinking hard about why he's unable to be a match for Oga, and tries to perfect a new special move, when Shiroyama realizes the crucial difference... Oga has a baby on his back!

Oga hears about the legendary Tojo, the final and strongest member of Ishiyama's TKKH, from Furuichi. And right away, he goes for a showdown!

Furuichi is called back from a resort on a tropical island where he was vacationing with his family to go to the public pool with Oga.

The Great Demon Lord decides to send Baby Beel some summer homework on a whim. The gang helps Baby Beel do the homework as best they can.

Baby Beel comes down with a fever, and Oga's link to him and his never-ending shocking comes to an end.

With a single blow from Tojo, Oga learns the difference in their strength and dejectedly returns home.

Oga is all raring to go finally beat Tojo this time, and Kanzaki and Himekawa try and join forces with him.

The battle to decide Ishiyama's strongest has started!

Baby Beel and Oga head deep into the mountains to help train Beel to get over his fear of bugs, where they run into Aoi and Kota.

Their work done, Doctor Furcas and Lamia head back to the Demon World, but Oga, Beel, and Furuichi accidentally hitch along for the ride!

In search of Alaindelon's daughter so they can get back home, Oga and the gang head to a city of criminal Demon Beast poachers to rescue her.

Oga and Furuichi head off to school to start the new term... except Ishiyama High is still completely destroyed thanks to a certain someone.
