The Detective - Killer 1, he has a gun, gun go bang, if you hit trick shots I will be insanely impressed even if it was bad.

The Twins (A) - Sage, your item shopkeeper. She is not your friend, likely soccer punch you in the gut and watch Dragon Ball on TV.

Model - OoooOooooOoOoo Hands

The Ref sheets were commissioned and drawn by Samuel Pastel

The model is being made by "pi" (I need to ask for their credit name aha)
