Rengo Orii is an avid superhero fan, with Megalith being his absolute favorite. Despite naysayers claiming the aging hero should retire, Rengo follows Megalith fervently, believing him to embody absolute justice.
But fate takes a strange turn when Rengo encounters a bizarre phenomenon and is transformed into an insectoid monster instead of the heroic figure he had always envisioned. Undeterred, Rengo embraces his newfound ability and resolves to become the hero he's always dreamed of being.
However, his lack of superhero finesse proves to be a hindrance as his immense strength threatens to harm those he seeks to protect. Rengo learns the hard way that Megalith's signature move isn't always applicable, especially when it risks taking someone's head clean off with a single kick.
Despite being a monstrous creature, Rengo's heart remains true and pure, fueled by his unrelenting desire for justice. But can a hero with a child's moral compass really fulfill the role they've always longed for?
