Irezumi is a TTRPG inspired by crime drama, particularly Yakuza crime drama. It is built upon the very simple but robust Caltrop Core system which I've 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. This book is 48 pages from cover to cover and is A5 (5.8 x 8.3 inches or 148.5 x 210mm) with art, layout and most of the writing by myself with a little help from some good friends along the way. It's my first every tabletop rpg design and a labour of love.
