FUNimation Entertainment describes Grimgar of Fantasy and Ash story as follows:
From A-1 Pictures, the studio behind Fairy Tail and Sword Art Online: When Haruhiro awakens, he’s in the dark surrounded by people who have no memory of where they came from or how they got there. As the darkness fades, a fantastic new world called “Grimgar” appears before them and their adventure begins—but first, they’ll have to choose their guild, class, and special abilities.
