Read the WN a bit, well, as much as has been translated. Starts off well enough though hard to tell how it turns out. Unfortunately, chances of getting licensed are very low.

MAL You can track down author, illustrator links from there.
GA Bunko Volume 1 There doesn't appear to be a dedicated series page.

Quite a weird series. It started as a silly and light-hearted read, but oh boy does it get dark occasionally later on.
While having below average quality of the prose, it is surprisingly well thought-out thematically, being one of the few series where "no killing" policy actually does make sense narratively. It also has a whiff of persian mythology, which is pretty rare in LNs.

It is also complete at 6 volumes, reaching intended stopping point.
