Apparently the series won't be written only by
Kaihou Norimitsu (it's author) but also by:
Kodachi Ukyou (Neppuu Kairiku Bushi Road original script sub writer, co-writing Gunslinger Stratos anime, Boruto the movie, writing Chaos Dragon)
Sakurai Hikaru (WAB visual novel series, Fate/Prototype novels, Fate/Grand Order writer, Psycho-Pass novel)
Higashide Yuuichirou (former "propeller" company writer (Ayakashibito), Fate/Apocrypha novels, Fate/Grand Order writer, Fate/Zero -Heart of Freaks- writer)
Fukami Makoto (Psycho-Pass writer, Yuru Yuri 3rd season writer)
Miwa Kiyumune (Steins;Gate novels, co-writing Gunslinger Stratos anime)
Morise Ryou (Gunslinger Stratos game co-writer, Gunslinger Stratos manga writer, co-writing Gunslinger Stratos anime, Cthulhu Mythology)
etc.
While these people are pretty cool and I understand that they were probably hired by Nitroplus (since Nitroplus is credited as a "script producer" and some of these writers are also working on Gunslinger Stratos anime) I don't really understand why would you need all these people to adapt already existing manga, with even its original writer on board. I understand that in Gunslinger Stratos anime case they had to think about a way to adapt the game's scenario but it shouldn't be that hard with adapting this manga series...
