Synesthesia (Prologue)
[2P!Canada X Reader]
Warning! This has a slight crossover with Canaan (the anime).

Sound to smell, color to sound, emotions and intents to colors.
That is how the world was in your senses.
Different, that you were.
Special, is what they called it.
Let us start this story back in time, when you were born.
You were born in [Home Country] with parent[s], and [siblings, if any].
Then, like the sparkling rain, it came down along with the terrorist organization, the illness that murdered your whole town/city. The survivors went insane.
But, because you were different, special, you lived with a special ability; that to use all your senses simultaneously.
After the government officials intervened, you were raised to be a weapon.
Your mentor was Oliver Kirkland, a cheery blond, British fellow. He was childish, bubbly, often made cupcakes (but most of the time, they were poisonous). He constantly smiled, and didn’t take criticism all that well. He carried a knife and knew how to use it. He was in the top 4 most experienced and strongest assassins working for a legal organization. Of course, all these top 4, at first, were rogues and rebels. Due to some rehabilitation and many threats, these beasts were turned into a fearsome weapon.
You also had a fellow student, also an apprentice of Oliver’s. His name was Alfred, but you called him Al most of the time. We was very smart, in some sense, and very blunt. He was one who did as he pleased, weather or not you liked it. The two of you had a very sibling-like relationship. Although, your squabbles did usually end in bloodshed.
And then there was Matthew or Matt, as he preferred. He often switched from being Oliver’s apprentice to another strong man known as Francis. He kept his blond hair long and in a ponytail, had a slightly stubbly chin when he started growing facial hair and wore a canadian monty uniform. He’s somewhat of a quieter version than Al, and one of your biggest rivals.
Last but not least is Francis. He is a frenchman, whose fighting skills were on par with Oliver’s. His face is rather grey and his hair is unkept in loose faded blonde locks. His eyes constantly look tired and he smokes often. His ability in battle to you still remained a mystery due to his emotionless facade, but with your special skill, you could tell he was strong.
No one really knew why Matt would switch mentors all the time. Not that it mattered- because when he left, something in the atmosphere of your world would change. All of it felt lighter.
Anyways, you grew up under Ollie (you called him that nowadays), Al and occasionally Matt, going on missions for various politicians around the world.
Until that day came when you were to be an independent assassin.
“As your mentor, I declare [Alias/Name], and Alfred to become full fledged assassins. From now on, you will work on your own. Who knows, maybe the next time you see me, we’ll be enemies. Good bye and good luck.” 
And with that, you took your own path.
Soon after, you heard that Matthew had graduated.
At first, you took random jobs for people you could find, making sure to cut all ties with the government as you did.
However, after a year of going from place to place, a rumor sparked up of a criminal organization. It was known as ‘Red Leaf’.
This terrorist group was planning on reviving the virus that destroyed your village.
And so, you sided with an anti-Red Leaf group, earning you your first, stable job.
As the best fighter in the anti-terrorist group, you were expected to go out on the field several times. All of them which you had killed numerous amount of people, but still not found out the leader.
Until that day when you were boarding a train on your way to a town said to be hiding their headquarters.
And there, grinning from the dark, stood your life-long rival.
There, pointing a Walter GSP straight at you, was Matthew Williams.
