Carlo Santos from Anime News Network said it had "unfolding in unexpected ways [...] and treating us to an ever-expanding universe." Santos praised the intensity of the art, saying Yoshinori Natsume is the opposite of Rumiko Takahashi and Mitsuru Adachi due to his artwork with "sharp spikes and jags, thick-lined penstrokes, and intense contrasts of black and white." However, he noted this prejudice the character designs and the panel layouts.[8] In another review, Santos praised the fact of Natsume pours his personal philosophy as a creator in the manga: "Of course, just being an exciting, well-paced fight scene doesn't hurt either—but being framed as part of the eternal debate between good and evil is what really completes the scenario."[9] Writing for Comic Book Bin, Chris Zimmerman called 'Kurozakuro volume 1 "a fascinating twist on the super natural genre" since "its premise seems right out of a shōnen title but its characters and the handling of their development is closer in substance to a richly layered psychological thriller rather than a smash-em up title." Zimmerman stated it is "compulsively entertaining" due to the gothic elements but said the artwork looks "simplistic and overly flat".[10] Leroy Douresseaux also from Comic Book Bin described it as "Harry Potter with a dash of Steve Ditko's The Creeper, and this dark fantasy and battle manga is worth your time", and he felt the series ended to early.[2] Kurozakuro has "an intriguing and dark plot perfect" according to ActiveAnime's Whitney Cox that also praised Mikito, the main character.[11] Also from ActiveAnime, Davey C. Jones enjoyed the "[c]ool moves, dire battles and secrets" but qualified the art as "chaotic".[12]
