Most people assume things by just believing their eyes. Most people, wait until they actually know it well enough, have solid proof to call it real. But some people, just feel it with their intuition. Call it sixth sense if you'd like, but we all have it.

But, most people don't believe this feeling they have on the inside, they must've known that this was an illusionary feeling, a lie, a misconception. Some don't believe in intuition simply because they were wrong before. Or, because they were hurt by someone else.

But, you know what? Most of the time, this 'sixth sense' is actually right.

What do you mean when you call a person a 'monster'? Is it because you think they're ugly? Or is it because you think they're inhumanly strong, or smart? Well, it's actually because each person has a demon inside them.

Something each person wishes never to reveal to anyone.

Our demons are embedded deep inside our hearts. We all have darkness, and we all have had our share of bad days.

Most people are good at hiding these demons.

Some are not.

Some like…Shizuo Heiwajima.

Well, since he is the main character of our story, let's get to the point, now shall we?

Shizuo Heiwajima was roughly very famous in that small town by the name Ikebukuro. He was quiet, mysterious and a dyed blonde man wearing a bartender's uniform.

But, some people call him monster because of his anger issues.

You see, Shizuo has a very low temper. And it's because of that he can't stand it when someone irritates him. His inhuman strength scares people off, and it's something he cannot control.

At least, he didn't learn to yet.

And there he was, one afternoon, when a few men from the Yellow Scarves bumped into him not knowing who he was. The man who had a yellow bandanna, taunted Shizuo.

…That was probably enough to make the man angry.

Then a sign post flew.

The Yellow Scarves fled, but that wasn't the only thing which irked Shizuo. His eyes landed on someone he detested. Someone whose mere existence he could not tolerate.

Someone by the name Izaya Orihara.

"Izayaaaaa!" Shizuo yelled, grabbing a trash can from his left. The person, Izaya didn't turn to look at him, which made Shizuo even angrier.

Shizuo ran toward the male, so that he'd get the perfect momentum to throw the object, and end the dark haired male's life once and for all.

But as he got closer, something hit his brain.

'Oh shit.' Shizuo thought as he tried his hardest to stop moving. But…it was too late.

Her name was Mayumi Matsumoto. She moved into Ikebukuro to live with her grandfather, since her parents passed away. Her grandfather was her only family now, and being a 21year old writer, she couldn't possibly imagine to live on her own.

She walked through the streets of Ikebukuro one afternoon, with a map in her hands. Her father lived near Raira Academy, so it wouldn't be too hard to find the place.

Just when she thought she was lost, she stopped and checked the map. She heard yelling around her, and Mayumi assumed that it was just street brawls and she knew she had to stay away from it.

Her grandfather told her about Ikebukuro's reputation as a gang village.

Or that was what he called it.

Mayumi Matsumoto didn't ever expect anything bad to ever happen to her. She didn't expect to get tangled in a fight and she didn't expect to be hit with a trash can which is twice as heavy as hers behind her back.

Mayumi could tell she was bleeding.

But, there was no pain.

She could barely keep her eyes open and she saw that someone was carrying her and running as fast as they could.

Her last thoughts before she fainted were, 'How can a trash can fly?'

A/N: This whole story is based off the song 'Demons' by Imagine Dragons.
I would really appreciate it if someone would review for the first chapter, makes me happy!
Shizuo is one of my favorite characters in Durarara! and I thought writing a story about him seemed like a good idea, since there weren't many about him.

The girl, Mayumi Matsumoto is my OC. Her appearance will be explained in the upcoming chapters. Just to say, she has dark short hair. And from the back, Shizu-chan thought she was Izaya.

Read and review~ :)
