May not go that long. There's only one volume of the source LN released (back in September) and, as far as I'm aware, nothing has been said about either when or if there will be a second.
EDIT: Overlap has announced V2 for next month.
Honestly, I think one of the author's major themes in the series (beyond exploring his endless series of fetishes) is the presentation of Kousuke as a stand-in for late-war and post-war America. He rarely feels Japanese at all.
