Thirty-six students find themselves and their school building suddenly adrift in a void-like dimension. When supernatural powers awaken in some of them, a sense of detachment begins to divide the group. Despite the student council's attempts to impose order, they clash with the students possessing special abilities, who rebel against their strict control.

This conflict leads them to discover that this world has its own set of rules—and following them is necessary for survival. After one of the students decides to take a leap of faith, the school switches dimensions once again. While they deal with the unique challenges and circumstances that each world presents, the students must unravel the mysterious phenomenon and find a way back home.

Rarely does a piece of media affect me as much as Sonny Boy has. The plot doesnt make much sense, in my opinion, but that is not the thing I loved about it. I was in a bad mental place when I watched it and the shit Nagara goes through just felt so real and authentic. This def fucked me up big time.

Oh yeah, the music is insanely good, I mean one of the best OSTs to come out of an anime in my opinion. Favourite track being "Sonny boy rhapsody": nagara and mizuho ran, this track cued and I cried.

Mixed Feelings
First of all, this isn't a review meant as a message or advice to anyone reading this. It's more of a way of coping.

With that being said, Sonny Boy is a show i really wanted to enjoy and admittedely, there were quite a few aspects that resonated with me, such as the aesthetics, the soundtrack and the cloudyness in my head I was feeling while trying to understand what the story was trying to convey, or perhaps not even really to "understand" but to interpret it in a way of my own. I really enjoyed the mysterious atmosphere. The abstract presentation made it fun to ...

This anime was highly praised so I eventually got around to watching it, but it was profoundly disappointing. There are only one of two conclusions that can be reached: Either the author failed to convey anything meaningful or it was completely pointless to begin with. Why is this the case? Every episode starts with a mystery that is never solved and ends with a conclusion that has no meaning, and what happens in the middle doesn't matter. At best there are random scenes one may resonate with, and in parts there are interesting ideas, but as a whole there is just nothing there.
