The official website for the tokusatsu series Garo Project announced that the anime adaptation of the tokusatsu series has been greenlit and is now possible. Yasuko Kobayashi (Attack on Titan) is developing the original script for the series, but the title is still uncertain. The Garo Project began in 2005, with the series' first airing in 2006 and running for around 25 episodes.
The original story of Garo (The Savior in the Dark in English) is a Henshin Heroes-style tokusatsu produced by Touhoku Shinsha Film Corporation. A young warrior, Kouga, whose father was killed by monsters called Horrors, seeks revenge by becoming Garo, the Guardian Knight, the most powerful warrior of the Knights of Hell. He then begins to hunt and destroy these beasts, until one day he meets Mitsuki Kaoru, a painter who dreams of one day becoming a great artist. Kaoru's body was bathed in the blood of a Horror, and Kouga decides not to kill her, using her as bait, since the Horrors would follow her by the scent of her blood.
