I guess it's only girls who's weak and died.

nope, there is a burly man with axe that died, a skinny man with crossbow died, a groos perverted man died with his pant lowered, a show off knight died, and 2 nameless soldiers died...so its not only girls who's weak and died...mwahahahahahaha

Nah, it's just that their deaths are the only thing that's really had any significance so far. I mean, even when the MC died, he just came back to life.
