'All those years ago, back when we first met... why did you take me in?'
"I was on my way back from a contract - katana in hand - when I saw a little kid in a costume with a mask in hand, blood covering their arms. I looked at you, and I saw something special. A spark in your eyes. You don't remember that night, do you?"
'No. Not really. Only flashes.'
"I asked you where your parents were, and you pointed to the stars... When I looked into your eyes, I saw a child with no fear, no hope, no future, and nothing else to lose. But behind all that saddens, and pain... I saw a fire. I saw it burning in your soul; dimmed only by grief. I wanted to help. I needed to bring that fire inside of you back."
