Demon King

Midnight

Nearby a popular small town illuminated by street lights was a part of the town with several dojo's and public event buildings

One of which was a sumo ring with a loud commotion coming from inside but at this late hour and being on the far outskirts of town there were no people drawn towards it

Suddenly a large and very fat demon wearing a sumo belt smashed through the wall and began running away from the town being much faster then his size indicted

(Y/n) jumped out onto the street and saw the fleeing demon and looked back inside the building towards multiple young boys and girls

(Y/n):stay here! I'll be back!

He took off running after the demon clearly panicked

(Y/n):*chasing it like this, If only I could've killed it without getting those kids caught up in the fight! I wouldn't have to chase after it like a desperate reject!*

As he pursued the sumo demon down the street he ended up dashing past a lone businessman as he ran past his eyes locked with the lone man and the only thing (y/n) noticed odd about him was his piercing red eyes

The sumo demon vanished into the forest bordering the town as (y/n) ran in head first not slowing down in the slightest

(Y/n):*damnit, where'd the tracks go? It couldn't have just vanished.*

(Y/n) suddenly slid to a halt not seeing anymore tracks as he started looking around

A massive shadow suddenly covered him as (y/n) looked up and saw the sumo demon in the air over him

Sumo demon:blood demon art! Iron body!

His skin changed to metal as he fell towards the ground and (y/n) flipped out of the way landed on his feet as the ground shook violently from the demon's impact

(Y/n):sound breathing...

He began inhaling as he leapt onto the massive demons back and tossed several bombs out in front of him

(Y/n):first form...ROAR!

He swung both blades down as he sliced against the bombs and the blades started going into the demons neck but the metal skin made it difficult

Meanwhile back in the town that line businessman entered the sumo tournament area and saw the 5 young children huddled together

He didn't seem emotional seeing children in that state though, he had an odd aura about him that was almost unsettling

Businessman:pitiful. Ryuk hasn't devoured anymore humans. Another fruitless demon.

He turned around as the children began whimpering still terrified from the recent fight

Little boy:mi-mister? Is that man with the earring coming back soon? He said his name was Tsugikono.

Businessman stopped at the hole in the wall as a child approached him from behind

Little boy:excuse me?
