Sorry, this is one of those animes that's mostly popular not because of the storyline.
If you're looking for fanservice well, you get your typical noticeable oppai, scantily dressed sidekick here.
I watched this thinking it's gotta be gamer-related & there's gotta be more to this story than boobs being pushed up by a blue ribbon.
Sadly, that's mostly all that's going on here.
Basically, a nobody forms a bond with a nobody goddess & together they become powerful eccentric nobodies.
Witness the shrieks from the oppai, loli goddess as she chastises & praises the main protagonist. If you're not into that (which I'm not) it's mildly amusing & gets boring quickly.
It's similar to SAO, but less plot, less harems & more boobs.
You're not missing much.
