I'm gonna tell you with absolute confidence that this'll be amazing!
I mean if they manage to screw up a series that is this funny, then props to them - they would have done the impossible.
If you haven't watched season 1 - do so NOW!!!
Why should you watch Saiki Kusuo no Ψ-nan 2?
Comedy - Its not your usual "MC likes grills and then gets beat up by grills for being huge pervert". Its more like "MC is a psychic who wants to be as far away from grills as possible"
Story - It's not any hardcore drama shayt - but it'll get you hooked on its hilarious
MC- The main character isn't a wimp, pervert or useless bastard. If you want that kind of MC go watch some 90's harem anime.
Just don't watch this shit when its midnight and your parents are in bed. I did, and my folks think I'm insane.
