He is a demon
An evil demon who tempts students and office workers into falling asleep right before class, work, or a deadline, making them late!
He also steals people's sleepiness and gives them insomnia!
What a terrifying [Bed Demon] he is.
But one day, the mighty Bed Demon was captured by an even mightier demon!
Its voice rumbled over the Bed Demon's head:
"Modern society has no need for sleep!"
"Only useless humans need sleep!"
It was the false god, the [Modernization Demon]!
After a battle lasting less than three minutes, the poor Bed Demon was deported.
He descended into a world crawling with pirates and gained a new name: Sleep Bed. His power was given a new name in this world: the Sleep-Sleep Fruit.
Sleep decided to rebuild the Bed Demon's fearsome reputation in this world!
"So, basically, humans should sleep more," Sleep said. "Would you like to worship me?"
The bubble at Garp's nose popped. "Oh, so you're a pirate?"
"No," Sleep shook his head.
As soon as he finished speaking, Garp fell asleep.
"..." A demon who couldn't fool humans couldn't gain power. Sleep had no choice but to give in. "Fine, I'm a pirate."
"Hooh..." The bubble popped again, and Garp opened his eyes. "Then there's no helping it. Surrender, pirate!"
"...What?!"
