The official Garo YouTube channel has posted a trailer for the upcoming anime.
Garo: The Carved Seal of Flames will air later this year and is to be written by noted tokusatsu writer Yasuko Kobayashi (Zero: Black Blood, Shinkenger, Attack on Titan) and directed by Yūichirō Hayashi (009 RE:CYBORG, Trigun: Badlands Rumble). Studio Mappa (Shingeki no Bahamut: Genesis, Hajime no Ippo Rising) will be in charge of the animation.
This will be the first anime adaptation for the Garo series, but not the first time a tokusatsu series has been adapted for animation. Past projects include the 1967 Golden Bat series, The Ultraman in 1979 (co-produced by Tsuburaya and Sunrise), the 1982 Rainbowman series, two Moonlight Mask series in the 70s and 90s, the G-Gundam-esque 1994 reboot of Red Baron, and the 2001 Kikaider: The Animation TV and OVA series.
