After he quit his gang, the yellow scarves, Masaomi always thought that the darkness of the city would disappear. Unfortunately, for this particular blonde haired boy this was not the case. New's of the leader of the Yellow Scarves 'retirement' had spread throughout the majority of the gangs in Ikebukuro. All of the gangs, with the exception of one, respected Masaomi's decision and agreed that they would not cause him any harm or make any trouble for the young teen so long as he was to stay out of any gang related events.
Ryouma Hatsuki, the leader of the red reapers, a gang that was situated just outside of town had other ideas for the young blonde. After he had heard the news of the child's retirement he knew that this was the perfect opportunity to gather up his small gang and rise up from the shadows to reap their next victim.

The rumor of the red reapers spread quickly throughout the city and before too long this information had found it's way to a certain male with dark black hair and it was safe to say that it had sparked an interest in him. The man curled up the corners of his lips slightly revealing a smirk with a dark expression on his face.
"This is certainly going to be fun" he cooed whispering in the darkness of the room.
It was a well known fact that Kida didn't like Izaya, they had a rough past and the events had affected Masaomi significantly mentally. The way that he liked to explain it was 'Izaya fucking him up big time' and 'Screwing up his life'. A few months had passed since those events and Masaomi felt like he was starting to escape his past and get all of his priorities back on track. However, it was just at this time that Izaya had decided it would be fun to wriggle his way back into the young boy's life. Oh, how Izaya loved to mess with Kida as much as he possibly could.
It had been a few days since Izaya had heard the news of the red reapers plans. The dark haired informant sat at his usual place in his office his head leaning on one hand as he stared at the screen of his laptop sitting directly in front of him while the other hand lazily worked at the mouse scrolling past a bunch of useless information that did not interest him.

Meanwhile, Kida found himself stuck at the end of a dark alleyway a wall behind him and a group of no more than ten angry looking boy's around the age's of eighteen and twenty. Masaomi could tell that it was a colour gang based on the red symbol stitched to their jackets and it seemed this this gang wasn't too please with his decision to leave his former gang. The boy's walked closer before they used wooden sticks and baseball bats to beat Masaomi to the ground before throwing them away and kicking him in the gut and head. Masaomi saw the boy's start to walk away before the darkness swallowed him whole.

There is so much more to this story but this small part gives you a brief explanation as to what is going to happen. If you enjoyed please let me know and i'll continue the rest in my free time.
