Grimgar of Fantasy and Ash Novel Volume 20 features story by Ao Jyumonji and art by Eiri Shirai.

The sekaishu are everywhere, and people are dying left and right. For some, like Kuzaku and Setora, death is not even the end. With the No-Life King using Merry as a vessel, Haruhiro blames himself for the twisted state of the world-but there's light in the darkness. A much-needed reunion awaits him, and a new life is about to be born. Not only that, but an old legend about the sekaishu's origins may hold the key to saving Grimgar. Haruhiro and his friends must stand together and put an end to this threat once and for all!
