As a TTRPG player and occasional GM, if I didn't have a fantasy game in the works, I would try to make this manga into a (short?) RPG campaign... It would throw my group who are used to fantasy and military games completely off balance. Tehehe... Well. Gotta save the idea for the future.
And it's also interesting that I like this manga quite a bit even though normally I would actively avoid these tags. I don't even remember why I looked at this in the first place.
