The streets are filled with various kinds of creatures. Some have pink flesh with a pair of antenna on their foreheads. Some have big and pointed eyes that occupy half of their face. Some have long and slender limbs that have three, wiggly fingers.
The most eye-catching are the four who wore black, hooded cloaks that is covering their entire bodies. They look like four phantoms with their fast speed as they walk, crossing the street before they disappear around a corner, never to be seen again. Some would think that their eyes must have mistaken. But, since most of the creatures in the black market all wanted to hide their identities to do illegal deeds, the four who wore black, hooded cloaks were immediately forgotten.
