Before embarking on working full-time on Berserk, Miura worked once more with Buronson in this one-shot for Young Animal magazine in 1992 and I gotta say maybe I understand why he chose to just do his own thing after doing this one lol
Buronson's writing has been pretty sketchy since his Hokuto no Ken days, with his idealistic portrayal of the ubermensch-like protagonist in post-apocalyptic worlds, but in this case it takes a sour turn into a nationalistic rant about "the New World Order" taking over Japan's national spirit and dominating the world or whatever. The manga is so barebones in its presentation that the only thing you're supposed to pay attention to is how "superior" the Japanese race is when compared to all the other ones. It's pretty bad
Miura's artwork is still really strong, though. But there's very little for him to draw in this, aside from the protagonist's angry face as he rambles on about glorious Nihon to everyone he sees. So artwise this is not really worth it either.
I'd say at least it manages to keep a tense plotline with semi-interesting concepts (even if poorly fleshed out), and it's not too long or too short, so it ends up being not a terrible reading experience. Wouldn't recommend it though
