As the second series is a direct continuation of the first (still wondering why Wazarai had to make a second series), if you like #1 you'll definitely like #2. The author has another series about black people boxing the shit out of some KKK vampires in the 19th century, which sounds hilarious and awesome at the same time.
He's good at doing the whole unconventional sport boxing thing with historical flavor and memorable characters. Thanks for the uploads, fellas.
