Ergastulum is a place filled with gangsters loyal to four main families. A violent city filled with hookers, thugs, drugs and Twilights. Twilights are humans born with extraordinary strength and speed, but who live short lives and generally have a handicap to 'compensate' for their abilities. The Twilights are ranked according to their skill level and wear dog tags, and are often referred to as 'tags'.Nicholas is a high level tag and life-long friend of Worick (a 'normal') and together they're the Handymen. They do odd jobs around town (kill people, act as gigolos, etc) and are not loyal to any of the main families. Occasionally they help the cops solve particularly nasty crimes. The story mainly revolves around Worick and Nicholas as they try to keep the streets safe for their friends in an increasing violent turf war and as anti-Twilight factions try to kill off all the remaining Twilights.This show was definitely my kinda thing. The character development was good (for only a 12 episode series), the animation was good and the violence factor was high. Not a show for kids though or anyone looking for light-hearted entertainment. As for why I only gave it a 7/10, well without spoiling the ending, I'm thinking they already have a second season planned, or otherwise just dropped it due to budget constraints or a lack of interest, because it seemed very abrupt. Well worth a watch anyway.
