The fall issue of Kodansha's Nemesis magazine confirmed on Friday that the previous issue's chapter of Hiroaki Samura's Die Wergelder manga manga was actually the main manga's finale. The fall issue also began a spinoff series titled Je-Mao Nee-chan no Kui Shinbō...Banshi (Big sister Je-Mao's Eating Endurance... Certain Death)

Samura (Blade of the Immortal) launched the series in 2011. The action story revolves around battles over money between three woman: a "passionate psychedelic revenger" named Nami, a "china dress-wearing killing machine" named Je-Mao, and a female gang leader named Shinobu Aza.
