I have no idea.
I have these pages from the wiki which has the cover, the first panel and another panel. The wiki only has the first five chapters. It seems to have no difference with the anime.
Comic Walker has the first, the second and the sixth chapter for free: https://comic-walker.com/detail/KC_006463_S/episodes/KC_0064630000700021_E?episodeType=first
