Deku-All For One

Training Day

Blinking slowly, he looked at the mysterious man in a whole different perspective, he was Daemon the Demon King in flesh.

"Shiigraki will show you the ropes" said the man "I am tired"

"Yup, yup. Come along kiddo"

Still shaking from what just happened, he tripped and fell into Shaggy's arms.

"Whoa, careful kiddo!"

Waking up to a beautiful ceiling, decorated with many different paintings. Midoriya had no idea why or what he was doing here. Looking up he saw Shaggy's resting face, as he softly snoozed. The shadowy man noticed his awakement and snapped his fingers.

"Gah ok ok" said Shiggy waking up from his nap. Shiggy stretched and looked down at Midoriya.

"Ay, kiddo you still haven't told me your name personally"

Midoriya blushing stammered, "Er, my name is Midoriya, but you could call me Daemon"

"Daemon eh?"

"Oh if it's too much.."

"Nah, I was just thinking it was a cool nickname"

They ventured in the lush place, exploring every single room.

"So, how do you guys even afford this?" said Daemon

"Shush, that a secret" smirked Shiggyyell

Daemon looked in awe, each room was filled to the brim with luxurious items and more. After some time...

"Alright Daemon, let's explore your brand new quirk" said Shiggy in a basic training room.

"Oh right haha" said Daemon completely forgetting

They stood face to face, staring each other in the eye. After a pregnant pause,

"Err, ok to tell you the truth, this is new to me; you know teaching and all" said Shiggy "Master usually takes care of things like this and uh well oh wait let me tell you what quirk you got!"

"Blood mitupaple–!' said Shiggy biting his tongue in excitement

Daemon's eyes sparked in excitement ready to try out his new quirk.

"Oi, catch this" Shiggy threw a small knife and blood bag, "use this to try it out"

Slitting open the blood bag, blood started floating around Daemon. He imagined sharp daggers and opened his eyes to muddy daggers floating.

"Uhh, is it suppose to look like that"

"Not really! But, you'll get the hang of it!"

The night wore on and Daemon improved his dagger making skills.

"Wow! Its late" said Shiggy looking at this watch

"Oh, it sure is" Daemon said disappointedly

"Hey, let's switch contacts" said Shiggy, "You know, to keep in touch"

Exchanging contacts Daemon and Shiggy say their final goodbye and Daemon walks through the shadowy portal.
