Honestly felt like a pretty weak ending to a mediocre show. I'm just not really a fan of this world it seems, I watched S1 of the main series whenever it aired and while I enjoyed the MCs in this more (especially Pop, she's easily the best MHA girl) I still didn't really love it. No real hook for a S2 too beyond vague people in shadows with no threats, but I guess it's nice to see Koiichi acting more on his own.
