Set in an RPG world, humans are somehow teleported in and they play as characters.
The writing is pretty bad, but about what you'd expect from a manga for middle schoolers. The story revolves around a goblin who's max level (99) for a generic RPG, and so she can kill most everything without breaking a sweat. It's got too many tropes like a sex-obsessed demon who wants to hook up with "senpai" and the writing is too bad for this to be interesting. It sometimes breaks the 4th wall, but given the writing this comes off more as lame attempts as humor than anything else.
Skip this one unless you're a tween obsessed with RPGs in general.
