Starting July 24, 2026, the Red River collector’s edition will launch with volumes 1 and 2 in Japan.
The 10-volume edition is priced at ¥3,520（税込） per copy for volumes 1 and 2. Volume 3 onward will be released at approximately one volume per month around the 26th. Each book is an A5-size edition with pages rescanned, foil-stamped covers, and color illustration galleries.
A promotional video narrated by Hiroki Nanami, who performs the anime’s opening theme and voices narrator/Himuro, has also been released. The Red River TV anime airs on Nippon TV in the AnichU slot every Tuesday late at night and on BS Nippon TV every Wednesday at 24:00; broadcast times may change.
AniHeat's take: Worth noting for fans of the anime and Chiho Saito’s manga: the collector’s edition offers a larger format, restored scans, color galleries, and a commemorative narrated promotional video.
