Sirius crouched on top of the rooftop, one eye closed and another looking into the scope of his rifle. The metal finger gadgets allowed him to pull back on the trigger without much movement whatsoever.

"Hah ! See ? My gadget just makes it easier, here I'll teach you."

Sirius smiled, holding onto your hand as he slid on the metal fingers on yours. One would wonder how a man like him worked in a field like this. There were no sane person who wanted to be an agent for "The crows" as they expected full dedication and loyalty which meant that you get very busy with work.

While other agents were sick of life, leaning against the wall with their eyes half closed, their heart half at home, Sirius was smiling.
