About Sonny Boy
Sonny Boy is a 2021 original anime series produced by Madhouse and written and directed by Shingo Natsume. Without warning, an entire class of students and their school building are cast adrift from the ordinary world into a shifting expanse of empty dimensions. Cut off from home and from the rules of reality they once knew, the students must learn to survive together in a void where space, time, and physics no longer behave as expected.
As the drifting continues, several of the students manifest strange and unequal abilities, from compasses that point toward escape to powers that can reshape the spaces around them. The series follows the withdrawn, watchful Nagara and his classmates as factions form, leaders rise, and the group fractures over how to use their gifts and whether returning home is even possible. Each new dimension functions less as an obstacle than as a thought experiment about freedom, rules, and responsibility.
Abstract, philosophical, and deliberately elliptical, Sonny Boy uses its science-fiction premise as a frame for a coming-of-age story about adolescence, belonging, and the search for meaning in an indifferent universe. Across twelve episodes it favors mood, ideas, and ambiguity over conventional plotting, building toward a quiet, open-ended meditation on growing up and finding one's own way forward.
