Damn, what a mid ending. It manages to give Saiki a satisfying conclusion to his personal character arc, but then sidelines the big reveal of his powers to "and then his friends accepted him. Probably. Maybe. Offscreen." Like... ya, I know. I've read the Manga, I know his friends care about him and would accept him for who he is, but I still want to see it. It's the climax of what is arguably the main plot of the series, show it to me. Let me see their reaction and the aftereffects of them adjusting to this new side of Saiki.
Not to mention that the author started a romance subplot in like chapter 5 and then turned it into a love triangle halfway through the series, and the finale to that is "Maybe they get together, idk." I want to see it happen. Please. Personally, I'm pretty sure he gets with Teruhashi, she just gets so much more attention from both the author and Saiki himself to lose the miko, but I still want to see it happen.
Whatever. The series was good. I had a lot of laughs. A poor ending won't ruin that for me.
