This show takes the superhero origin story and snaps it in half for laughs. Suzuo gets handed an experimental power suit, told to fight actual criminals, and has to keep his civilian identity secret from the people literally living with him, a setup so fundamentally broken that every episode finds new ways to exploit it. The comedy isn't trying to be clever about it; it's watching a teenager in a diaper suit fumble through being a hero while everyone around him is somehow worse at their job than he is.
Suzuo is a broke nineteen-year-old desperate for work when the Galaxy Federation Police recruits him for their latest scheme: testing a prototype power suit that turns him into Dokkoida, a ridiculous superhero with a diaper aesthetic. His job is simple enough: fight criminals, prove the suit works, collect a paycheck. The catch is that Suzuo and his opponents must never recognize each other outside of costume, or the entire test gets invalidated. That becomes a problem when the Federation stashes everyone involved in the same apartment complex to cut costs, forcing Suzuo to attend school and work regular shifts alongside the very criminals he's supposed to be fighting at night. What unfolds is pure comedic chaos. Suzuo stumbles through his double life while increasingly absurd A-class criminals keep showing up as his neighbors, coworkers, and classmates. The suit itself is ridiculous, the fights are over-the-top, and the premise collapses under the weight of its own stupidity in the best way possible. This is comedy that doesn't take itself seriously for a second, backed by constant action and the kind of weird sci-fi logic that makes everything funnier.
