Western Crossover: Little Beel’s Vacation Assignment to Conquer the World

"Once upon a time, in a place far, far away, there was a handsome, charming, and kind-hearted young man. As the kind-hearted young man washed clothes by the river, a huge middle-aged man came drifting down from upstream. Without hesitation, the kind-hearted young man pulled the enormous man out all by himself. Then he split him in half, and a baby popped out." Two human-shaped lumps of charcoal collapsed abruptly to the ground. Amid the baby's cries and the motorcycle's mournful howl, Oga weakly explained.

The other, two-hundred-pound lump of charcoal could no longer hear anything. All he wanted was for the baby who was crackling with electricity to stop.

"Hey! Baby Beel! Men have to be tough! It's just a hot dog that fell on the ground! I'll buy you two whole ones later!!!" "Dabu!!!!"

This is the story of an "ordinary" delinquent high school student who becomes the adoptive father of the Demon King. After an accident brings him to Crime Alley in Gotham, Baby Beel's path to conquest begins.
