Unlike mainstream anime, Kuroinu has no official home on Crunchyroll, Funimation, or Netflix. The only legitimate English-licensed release came from Kitty Media (a sub-label of Media Blasters) in North America. They released a DVD box set titled “Kuroinu: Shadow of the Dark Fortress” – but crucially, it only contained Episode 1.
