The Familiars of Black Japan

From publisher blurb:

Black Japan is a weird setting, and even the familiars owned by its spell casters tend to be a little strange. Living garage-kit models, lewd fairies, pitiful child-ghosts and even living tendrils made of animated feces are available familiar options. The new familiars presented here are fairly common among Black Tokyo’s spellcasters. In many cases, these statistics can be used for normal creatures as well.
