Welcome to the fandom! I feel that people who have discovered a great anime early are lucky because they don't have to binge watch for weeks, or even months, to catch up. By the way, I also love Hirato/Akari. It's funny.
I have to wait for almost a year every time because I'm not into the Karneval anime but the manga (TwT) I fell in love with the manga some years ago. I was excited when I heard it'd turn into anime, but after the first episode (which was awesome), I didn't like how they animated the rest.
Well. I didn't read the anime(but my sister did!) so i don't know. But I liked the music alot. i understand how the art in the later episodes were sort of weird, not exactly like the first episode. But that's what happens when the anime people get to it.
