Yen Press has announced that it has licensed artist Tsuyoshi Takaki’s Rose Guns Days Sorrowful Cross Knife, the prequel manga to Ryukishi07’s original Rose Gun Days manga. The company will release the manga digitally on February 21, 2023.

The manga is described as:

1946, two years after the war ended in Japan. An orphan named Wayne has been hired by District 23’s Club Primavera-the base of operations for the brothel alliance vying for power with foreign militaries and the mafia. When a series of murders strike fear and rage in the people of District 23, the prime suspect is none other than Jack, the orphan boy Wayne sees as his brother. Torn between belief and doubt, Wayne struggles to find the answer to the mystery before him-who exactly is Jack? The culprit… or just another victim?

Takaki and Ryukishi07 launched the Rose Guns Days Sorrowful Cross Knife manga in Square Enix’s Monthly Big Gangan magazine in 2012, and ended it in 2013.
