Sequel seasons pretty much ruin even the most beloved of series.
But not with Magical Boys, now this is how you do a sequel. Which is basically to give us exactly the same thing as from season 1.
Having said that, Magical Boys S2 is particularly good in reminding us of all the running gags we may have forgotten while only slightly ramping up the gayness and bukkake-ness of the first season.
I think the key to spotting a good second season vs a terriblefuckingpieceofruinousshitstain is in the number of !. If they stick to just one !, then the second season’s good. If they add a second ! like in K-On!/K-On!!, then it’s the latter.
tl;dr, I dig Binan Koukou Chikyuu Bouei-bu Love! S2 episode 1.
