Justaway is a recurring gag character and explosive-themed mascot-like object in Gintama, rather than a traditional human character. It is presented as a small, round bomb-shaped item with a cheerful face, often used for comedic effect and absurd situations. The name appears throughout the series as part of the show’s parody-heavy humor, becoming one of its most recognizable running jokes. Justaway has no conventional personal identity, but it serves as a memorable symbol of Gintama’s chaotic, self-aware style.
