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 only thing I don’t understand about Sonny Boy is what other people don’t understand about Sonny Boy. The story is a reimagining of The Drifting Classroom, only now, some of the students lost in limbo have thematically relevant superpowers. People all over the anime community have given this show a reputation for being abstruse, or “2deep4u” as the saying goes, but I could not disagree more, and in fact, I actually think the show almost suffers from being too simplistic. Sonny Boy is a metaphor for entering the Japanese school and work system, and the emotional issues of these characters stem from their middle read more

Sonny Boy is an experience. A philosophical, poignant, and inventive experience.

It would be pretentious to say, "this anime isn't for everyone." Sonny Boy is accessible to everyone, but it demands patience and an open mind. If you're willing to solve this puzzle of an anime, the payoff is worth it. Rewatching it, you will notice clever foreshadowing, irony, and metaphors within the complex story and mesmerizing visuals.

Sonny Boy is about an entire class that suddenly shifts into the void—comparable to a sci-fi take on Lord of the Flies. Out of the thirty-six stranded students, a couple dozen of them gain mysterious supernatural abilities. The students read more

Here is my very own, humble, spoiler-free take on Sonny Boy:

Sonny Boy is an anime that had a lot of promise, and quite frankly, it absolutely delivered. Likely inspired by The Drifting Classroom, Sonny Boy is the surreal story of a class of students that is sent adrift into a void-like alternate dimension. With a touch, but not much focus into its fiction, Sonny Boy explores the relationships between charismatic, captivating characters and the inner challenges they face along the length of the story.

Admittedly this anime is not for everyone, but it stands out from the bunch. Watching this anime weekly the pace already felt read more

“You’re going to go adrift. It will be into a world governed by the absurd.”

Sonny Boy is dense, messy, and sometimes pretentious beyond thematic purpose. Watching Sonny Boy requires patience and thought. In one episode, the audience is expected to sit through an entire five minutes of one character just talking about monkeys and baseball, and unless you’re someone who is either decently knowledgeable in baseball strategy or who is particularly fond of long metaphorical narrations, I don’t see how that could be appealing. Throughout its seasonal run, the show constantly divided the anime community, often sparking new chances to usher in the age-old conversation read more
