The manga edition is authored by Katsumi Michihara, and is derived from the first two volumes of the original-novel. This manga story is faithful to the original, possibly more faithful than the anime. However, there are some changes that could be considered major, e.g. the gender of a character is changed. Akira Kasahara is cooperating in drawing mechanics.
