It had an Anime adaptation in 2008.
During the Japan Content Showcase held in Tokyo, Craig Kyle (Thor: Ragnarok Writter and Thor Producer) announced that he is working on a live- Action televisión series based on the manga of Ga-Rei.
The Hollywood reporter said as follows:
“Kyle, who currently runs Yugen Entertainment with partner Tim Connors, in a keynote appearance said he was currently developing a live-action TV series version of Hajime Segawa’s Ga-Rei, telling the story of two young girls “destined to define the fate of the living and the dead.” He said that he was working on the pilot and flushing out a character bible, signaling that the show could unfold its story over several seasons.”
Kyle also said as follows:
“He also said the deal he struck for the option to develop the manga “is very reflective of the depth of the properties that you can offer the international market.”
“What it has more than anything is wonderful, wonderful characters,” Kyle said. “That’s the one component, above all else, that will guarantee a success if handled properly by those you entrust with those characters and the IP. Everyone who wants the next Game of Thrones, I will make the bold statement that Ga-Rei has that potential.”
“I left Marvel with all my friends intact...I wanted to touch far more worlds than the ones I had been exposed to for 14 years,” Kyle told the crowd about why he founded Yugen. “The best place to find those great stories is here.... [Japan has] a treasure trove of material that you can pull from.”
He said: “The Japanese stories and characters that have appeared since before I was a kid have far exceeded those that we have done in the States. When it comes to gender, the diversity, on all levels fearless choices are made.... [The characters have] so many tremendous shades of emotional and sexual and personal gray. They’re just bold.”
Kyle’s conclusion: “You own the vault.... You guys are the promised land.”
Kadokawa has published the series and describes the story as follows:
“Kensuke Nimura has always been able to see spirits, but he never expected to find himself helping a girl named Kagura who battles evil spirits with her spirit beast, Byakuei. As it turns out, she’s a member of the Ministry of the Environment’s top-secret Occult Disaster Response Agency, and she’s out to recruit him, too...”
