Irezumi is am RPG inspired by crime drama, particularly Yakuza crime drama. It is built upon the very simple but robust Caltrop Core system which has been modified to give you a game about loyality and ambition, of tragic ends and climbs to power. Where your character progresses and is reflected by the ink that they have on their body as they rise through the ranks of their Yakuza family.

Irezumi is a rules light game intended for story telling with a GM and a group. Players make the organisation the work for, they all form part of that criminal organisation from the early days of their career, to the fading twighlight if they even live that long. Prison, rival gangs and even the brutality of your own superiors are all things that need to be overcome.
