A mad scientist decides octopuses deserve to rule humanity, so he kidnaps an idol singer who happens to be your secret superhero partner, except you don't know that yet. Perman has to fight a giant octopus while also protecting the girl he likes without realizing she's been saving his life the whole time. The movie finds its comedy in the gap between what each character thinks is happening and what's actually happening, turning a B-movie premise into something that lands harder because the emotional stakes are personal, not planetary.
A mad scientist obsessed with octopuses hatches a scheme to prove eight-legged creatures deserve to rule the world instead of humans. His first move: kidnapping Sumire Hoshino, a beloved idol singer, to use as leverage. What Dr. Octo doesn't know is that Sumire leads a double life as Perman, a superhero fighting crime across the city. When Mitsuo Suwa, Perman's teammate, learns that his crush has been taken hostage, his emotions override his usual caution. He transforms into his Perman form and charges headfirst into battle against a colossal octopus creation. What starts as a straightforward rescue mission spirals into comedy and chaos as Mitsuo discovers that fighting a giant monster is far messier than he anticipated. This film blends action-packed sequences with humor, balancing genuine stakes against absurdist comedy. Fans of lighthearted superhero adventures will find plenty to enjoy, especially those who appreciate jokes landing through character mishaps rather than cynicism. The movie delivers simple thrills wrapped in earnest sentiment about protecting those you care about.
