I am unable to generate a news article confirming the ending of Kenji Okamura’s Touken Ranbu: Nihongō Tsurezure Sake spinoff manga at this time. Extensive searches for official announcements, final chapter details, or news articles specifically stating the manga’s conclusion did not yield definitive information. The available search results primarily consist of listings for collected volumes and general manga database entries, which do not confirm the serialization status as “ended” with a specific date or chapter.
