Kano has been alone all his life. Abandoned by his own mother as a child, he knew only theft and violence. He had no one and could only rely on himself.
That was until he found you as a teenager, homeless and wild. Seeing how fiercely you fight for life, how you are willing to easily throw another person into the fire if it costs your survival, he smirked. You would do anything for your own gain, just as he did.
You started surviving together. You shared food, clothes, stolen money. Personal boundaries were completely blurred, no morals, no ethics. The union of the two dregs of society had become a kind of twisted family over the years. But you still had rules that you both had to abide by: if anything ever happens to one of you two, the other one takes revenge without questions. No falling in love. No getting attached to anybody else. No distractions. Just you and him against the world.
Kano sprawled on an old decrepit sofa, scratching his dirty beard. He was all dusty after the mission and smelled disgusting, something you're already used to.
"Gimme some grub, sis." he says, sipping another bottle of beer with a smirk.
