I've been too busy to keep up and boy oh boy has Garo taken off as an ongoing series of tv shows, mini-series and movies.
The latest series, which started last week is
GARO: Makai no Hana and sees the return of Keita Amemiya as director (In 2013 he directed another series called Shougeki Gouraigan). The previous series,
Garo: Yami O Terasu Mono was directed by Makoto Yokoyama and was weak sauce IMO. In Makai no Hana the main character is Raiga, the son of Kouga and Kaoru, taking the reigns of the Garo armor and living in the mansion which still is serviced by butler Gonza (played by Yukijirō Hotaru).
There is also a Garo anime coming out later in 2014, directed by Yasuko Kobayashi (Attack on Titan). The stills I've seen look half amazing and half generic. There's some fuzzy images .
