All good things:
Main character isn’t OP
There is no harem
The language isnt bad at all
The rest of it:
Main character is an idiot… Constantly confused, asking relentlessly useless questions, never picks up on basic information presented to him.
As the reader I’m always baffled at his personal choices of who to trust and when to trust them, what he thinks is true vs what he thinks cant be the case… I think its more of a failing in the writing than it is specific character design.
Other characters are either pretty basic or seem to only exist to say terrible lines that provide classic story tropes.
None of it bad, only ranging from sorta interesting to mildly annoying…
If like me you are now 250+ books in (mostly LitRPG or fanatsy/sci-fi) this is not a waste of a credit, but can always be shoved down on any list you have
