God Vs Heroes (BNHA x Death Note)

A New World

"So how did you make a deal with the King of Death?"

A large demon with wings followed a young man. The man wore a bloodstained suit, with small holes in the shapes of bullets. His name was Light Yagami. His companion was Ryuk, a god of death. They walked on a gray valley, filled with debris and bones. This was the shinigami realm, a wasteland.

"I offered my intellect to restore the shinigami realm in exchange for eternal life."

"And he accepted this deal?"

"No." Light and Ryuk started to descend down a large staircase. It spiraled under the ground. Rusted chains flowed along the walls, the red rust the only colored thing lining up the gray brick walls. 

"Oh... well, can't say I'm surprised." Ryuk shrugged as he ate an apple he had brought with him from the human world. He was running short. 

"But he did give me a chance to prove myself."

"Oh?"

"I was able to become God of the New World once. He wants me to do it again, this time, watching how well I do. To prove to him the power of Kira. But, there is a twist. This time, it is an entirely different world, far away in the cosmos. It's a fresh starts"

"My... that really sounds interesting."

"It does. I never considered the multiverse theory to be correct. This experience will certainly be educational. And you're coming with me."

"Huh?"

"You were with me when it all started right? It's only fair."

"I suppose I'll enjoy watching the show. And maybe try out some apples from this world."

"Yes. A fresh start. With no L, and no Near. Oh yeah, and Matsuda to shoot me to near death. This will be easy. Just as long as you don't write my name again"

"Hey, no promises." The shinigami laughed.

"Just keep me entertained."

Light looked over the portal. It shifted it's colors, and shone an unusual golden color. It must be changing itself to enter a new place entirely. 

"Yeah, this it it."

"So do I just go in or-" Light began.

Ryuk just gave him a shove. Light tumbled down the portal, and he found himself in a large blue sky, the ground a terrifying distance away, but coming closer.

"KYAH! Ryuk! What the hell are you doing?!" Light screamed as he plummeted through the sky. He zoomed in past the clouds, and he looked in panic at the rapidly approaching ground. He continued to scream until Ryuk finally caught him. The god of death laughed as he flapped his wings.

"Geez, you're pretty loud, kid." The shinigami snickered. They glided threw the night sky. It was raining, but the view was nice. They were above a forest. In the distance, he could see a city.

"You know Ryuk, if I didn't know any better, this world doesn't seem to different from home."

"Heh. Well Light, you'll see what's up soon enough."

Then Ryuk dropped him. There was no time to react. He fell through the trees of a forest and landed in the mud with a thud and a loud crack.

Light had broken his arm.

A scream emanated from the fallen god. Several crows fluttered away at the sudden sound.

Light's face panted a few times, looking at the damage. It was twisted badly. He took of his jacket and tied it up to support his arm. His eyes darted to stare at the Shinigami.

"What? It's to make the whole 'saving' thing more believable."

That's right. The king had instructed him on how things would go.

"Still, I can't help but feel pissed off. Could at least have given me a warning."

Everything has been set up for you. In this world's version of Japan, you now legally exist. There will be nothing off but your sudden appearance in the eyes of the law. Now, all you have to do is pretend you've been hurt and call for help. Then observe, and watch how different this new world is.

Well, he didn't need to fake the injury. Light looked around at his surroundings. It looked like he was in a small forest. He could see a building in the distance. Reminded him of his school years ago. Speaking of which- he looked down at himself. He looked smaller than before. He was at a high school age again.

"Interesting."

"Say, this place looks nice. Shame there's no apple trees, though. Promise you can hook me up with some later?"

Light used his good arm to check his backpack.

He had been supplied with everything. Identification, birth certificate, a small amount of money. And a brand new Death Note sat inside. Light smirked at the sight, with a gleam in his eye. He wouldn't make the mistakes he made before. This was a second chance. He would become the God of this world, and everyone would bend to the will of Kira-

"Hey! Are you alright?"

Light quickly closed his bag and turned around. A young boy ran at him, looking concerned.

This is it! His first integration with the universe! He had to fit in, learn everything that was different. He had to act like he knew all this before, or people will suspect something. Crap! What should he say? What would a normal person say in this situation? What even is the norm? He was overthinking it. Best to just greet him.

Light tried to push himself up, accidently using his bad arm.

"Aargh!"

"Don't worry! I am here!" 

"Oh, hey. I was just walking, and I fell down a hill on my arm. I think I broke it."

"I'll take you to our nurse! Her quirk will heal you up right away!"

"Quirk?"

The boy looked at Light oddly. Light immediately recognized his mistake.

Damn it! Why is he looking at him funny? What is a quirk? Is it meant to be common knowledge? Light's making himself look like an idiot! Quick! Say something! Anything!

"Of course! Uh, thank you!"

The boy smiled at him. He offered his hand.

"I am Deku! And you are?"

"I'm Light Yagami..."

Ryuk laughed in the back. His eyes gleamed red with excitement.

"This is going to be very, very interesting..."
