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.

The plot is pointless. Not pointless because it lacks coherency, but because the viewer should view this anime as the main character does: a tornado of nonsense happening in all directions without any purpose. If you try to burn your head with theories and explanations of events, you'll miss what really matters: the adventure.

From a scifi adventure point of view, this anime is a solid 10/10. A masterpiece of reality altering stories.

It's a 9/10 for one reason: it could be told in 5-6 episodes. Making it 12 just increases headache for no reason.

Please, watch the world as it unfolds, without trying to fit every piece ...

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.
