Kill Time Communication

Kill Time Communication is a Japanese publishing company whose publicly documented activities include manga magazine publishing and the release of collected manga volumes. The company is particularly associated with Comic Valkyrie, a science-fiction and fantasy seinen manga publication aimed primarily at male readers from their teens through their thirties. The magazine was launched in 2006 and developed from a print periodical into a digital publishing platform, illustrating the company's role in adapting genre manga publishing to online distribution. Comic Valkyrie began as a B5-format magazine issued every other month. Its first issue was released on July 25, 2006. The publication later increased its frequency to monthly issues beginning with volume 30 on May 27, 2011, but returned to a bimonthly schedule after volume 34 was released on September 27, 2011. Its final print issue was volume 40, published on September 27, 2012. After the end of the print edition, Comic Valkyrie continued as a free online publication through the company's website and through Nico Nico Douga's online book service, Nico Nico Seiga. The magazine's editorial identity has been described as a bishōjo battle-oriented title, with many stories centered on attractive young women involved in adventure, combat, futuristic settings, or fantasy scenarios. Its serialized works have included Freezing and several related titles, as well as series such as Management of a Novice Alchemist, How to Build a Dungeon: Book of the Demon King, Dream Hunter Rem Alternative, Ziggurat, and Tadokoro-san. A number of series originating in the magazine have subsequently been collected under Kill Time Communication's Valkyrie Comics imprint. Comic Valkyrie's online publication ultimately ended with a final issue dated December 15, 2025. Titles that were still being serialized at that point were transferred to the KimiComi website. This transfer represents the latest documented change in the distribution of the company's Valkyrie-related manga activity. Public reference material supplied for this dossier does not establish Kill Time Communication's founding date, ownership, corporate scale, current executives, financial performance, or the full extent of its publishing catalog. Those fields are therefore left unspecified.

The publicly documented history of Kill Time Communication is closely linked to Comic Valkyrie, a Japanese science-fiction and fantasy seinen manga magazine published by the company. The available reference material does not provide a confirmed corporate founding year, founder, ownership history, or detailed account of the company's broader publishing operations. It does, however, document the development of Comic Valkyrie from a print magazine into an online manga service. Comic Valkyrie's first issue appeared on July 25, 2006. The magazine was issued in B5 format and initially followed a bimonthly schedule, with issues released on the twenty-seventh of the relevant month. Its editorial focus combined science-fiction, fantasy, action, and young-women-centered adventure stories. The publication was associated with a male readership ranging from teenagers to readers in their thirties, and it was characterized in contemporary coverage as a bishōjo battle magazine because of the prominence of female characters involved in combat or fantastical conflicts. The magazine experimented with its release frequency during 2011. Monthly publication began with volume 30 on May 27, 2011. This schedule was not maintained indefinitely: after volume 34 was issued on September 27, 2011, the magazine returned to bimonthly publication. The final print issue was volume 40, released on September 27, 2012. Rather than ending the editorial line altogether, Kill Time Communication shifted Comic Valkyrie to a free digital model. Full issues and individual chapters became available through the company's website and through Nico Nico Douga's online book service, Nico Nico Seiga. The title served both as a periodical and as a source of collected manga for the company's Valkyrie Comics imprint. Documented series associated with the magazine include Freezing and its related works, Freezing: Zero, Freezing Pair Love Stories, Management of a Novice Alchemist, How to Build a Dungeon: Book of the Demon King, Dream Hunter Rem Alternative, Ziggurat, Tadokoro-san, and numerous other science-fiction, fantasy, action, comedy, and mature-oriented titles. This magazine-to-book pathway gave serialized works a continuing life in collected editions. Comic Valkyrie's digital run continued for more than a decade after the print edition ended. Its final online issue was published on December 15, 2025. At that point, currently serialized titles were transferred to the KimiComi website. The transition marks the latest documented stage in the publication's distribution history, although the supplied sources do not clarify whether Kill Time Communication continues to operate independently, under another owner, or through additional publishing brands. Corporate details beyond its association with Japanese publishing and the Valkyrie line require further verification.
