Shuumatsu no Valkyrie Kitan - Jack the Ripper no Jikenbo

Shuumatsu no Valkyrie Kitan: Jack the Ripper no Jikenbo is a spin-off manga series that expands upon the narrative of the popular Record of Ragnarok franchise. Published by Coamix, the series focuses on the origin and mysterious exploits of the character Jack the Ripper, one of the most polarizing figures in the original tournament-style manga. By shifting the perspective to this specific historical enigma, the series explores the dark, Victorian-era atmosphere of London through the lens of fantasy-action, consistent with the stylistic intensity established by the parent series.

The series is written by Umemura Shinya, one of the creators behind the original Record of Ragnarok, with illustrations provided by Keita Iizuka. The creative team aimed to maintain the high-octane combat and intricate character design that fans of the franchise expect while anchoring the plot in a more focused, character-driven mystery format. Since its release, the spin-off has been received as a companion piece that deepens the lore of the Ragnarok universe, appealing to readers who favor the Victorian aesthetic and the complex moral ambiguity associated with the historical Jack the Ripper figure.
