Shūmatsu no Walküre Kitan: Jack the Ripper no Jikenbo #11

Shūmatsu no Walküre Kitan: Jack the Ripper no Jikenbo serves as a spin-off to the popular Record of Ragnarok series, focusing on the characterization and backstory of the Victorian-era serial killer Jack the Ripper. This specific installment continues the narrative expansion created by author Keita Iizuka and artist Shinya Umemura, who sought to recontextualize the historical figure within the series' supernatural combat framework. The manga aims to bridge the gap between historical mystery tropes and the high-energy action established in the main title, emphasizing psychological intrigue alongside period-appropriate aesthetic choices.

The publication is serialized under Coamix's Monthly Comic Zenon imprint, which has become a staple for seinen manga that bridges traditional historical fiction with contemporary fantasy elements. The artistic direction by Keita Iizuka maintains the distinct, sharp linework associated with the franchise, focusing on atmospheric depictions of 19th-century London to ground the supernatural narrative. Upon its release, the series has been received by the fanbase as a deliberate character study, praised for adding depth to one of the main series' most complex antagonist-turned-protagonist figures.
