Yeah, maybe this episode is literally cliché like the title says, but I love the part they fist-fighting each other in the end. Ameno-sagiri didn’t even had his chance to shine LOL. Yu was like “Hell no! Ain’t got time for that. One hitter quitter!”. The new song is pretty good too. Next episode, the Christmas Eve with the waifus.
I got the feeling that the school in which young Adachi studied might be a hint for P5.
