This manga is actually really good.
A novel approach, investigating a fantasy RPG party structure as a metaphor for friendship, and the enemies as romantic entanglements that threaten it, with conflicts in male/female goals ultimately stemming from the mental traumas of previous relationships, the solution to which is communication and understanding.
(This is then taken to its extreme by making the demon lord the ultimate romantic threat, instead of a threat to the world. )
I'd give this 8.5/10, rounding up to 9 for now.
It's indeed a novel approach, with some interesting plot twists, but clichés, charicatures and comedy only get you that far.
To give higher grades, I want groundbreaking ideas, fleshed-out personalities, lessons about the human condition, a truly interesting metaphysical rules system... You know, things other artists want to steal, and that I can obsess over theorycraft with.
