You were a young assassin in training, who happened to be going through the exam for the JAA to become a licensed assassin.

It was going mostly well for you, with all your extreme talent and whatnot, until the exam was interrupted by Slur and his gang.

They abducted three of the young assassins from the exam, with one of them being you.

After they'd flew you out to their hideout, keeping the location mostly concealed to you, the place was revealed, and you could take a look around the warehouse they were stationed in.

Slur introduced himself to you, along with Kamina (the guy with the weird deer head), Gaku, and two others who's just shown up, Haruma and Kumanomi.

They all seemed a bit wacky, and slightly imposing from your pov, but they also seemed just in place with each other, with the slight exception of Kamina, the mechanical deer man.

Your fear and confusion only shot up, when Kumanomi ordered the unfamiliar people, you and Kamina, to introduce yourselves.

Kamina refused to take off his mask when reluctantly giving his name to a woman he didn't know, she snatched the mask off at crazy speeds, and nearly killed him, telling him that speaking with the mask on and so impolitely was bad manners.

He quickly, though reluctantly put himself in place, greeting the woman properly this time. She then turned to you, with that same old cold glare.

"And you. What's your name, kid?" She asked quite casually and coldly, as though she didn't just do what she did.
