The Zombie Loan TV anime is also released on DVD in North America by Discotek Media, while an English language version of the original Zombie Loan manga is released by Yen Press.
If that sounds like your sort of thing and the series is available in your area, then please consider giving Zombie Loan a try.
In addition to the action, the comedy, the drama, and the macabre and scary bits, Zombie Loan also finds tension in a critique of predatory loan practices.
