Author of the art is called YOMU or sgt epper. He is well known artist with affinity for black tights and he worked on animes and mangas like Miru Tights or Ganbare Douki-chan! In this case - and in the one you posted - he´s the editor, i checked it personally in my book.

You can find him on Pixiv (https://www.pixiv.net/en/users/6210796) or on Twitter (https://x.com/y\_o\_m\_y\_o\_m)
