DeNA’s MangaBox site published the 103rd and final chapter of Kaishaku’s Red Blood Red Legacy (Akaaka Toshita Chi no Monogatari) manga on March 10, 2017. MangaBox has also published the final chapter in English.
The story of the manga is described as:
Itsuki and Hayato, two brothers who grew up in a village nestled deep in the mountains, set out to hunt down a wolf that has been attacking the livestock of the village. Itsuki is about to go in for the kill when a gigantic beast appears out of nowhere, snatching up the wolf in its jaws and sucking the life out of it. The beast that stared Itsuki down was a gargantuan, blood-sucking vampire deer… will the two brothers be able to return to the village alive?
Kaishaku launched Red Blood Red Legacy in DeNA’s Manga Box smartphone app in Japanese, English, and Chinese in April 2014. Kaishaku consists of artists Hitoshi Ota and Terumasa Shichinohe. The duo’s other manga include Steel Angel Kurumi, Magical Meow Meow Taruto, UFO Ultramaiden Valkyrie, Key Princess Story: Eternal Alice Rondo, Kannazuki no Miko: Destiny of Shrine Maiden, and Kyoshiro to Towa no Sora (Shattered Angels).
