Mask is a minor supporting character in the manga and anime series Joshiraku. The character is best known for always wearing a wrestling mask, which gives them a mysterious and playful appearance. Mask’s background is largely unexplored in the series, and they serve primarily as a recurring friend to the five main rakugo girls—Marii, Kigurumi, Tetora, Gankyo, and Kukuru. Their personality is enigmatic and adds to the comedic atmosphere, as the character often reacts to or participates in the group’s rapid-fire conversations without ever revealing their face or clear motivations. Mask’s role in the story is to contribute observations and reactions, blending into the backstage and location-based sketches that define the series. Key relationships are limited to the core group, with Mask functioning as an accepted but oddly dressed companion. The character does not undergo any notable development or change over the course of the series. Their most distinctive feature is the wrestling mask itself, which may be used for gags or physical comedy, but no special abilities or powers are associated with them. Overall, Mask remains a lightly sketched figure whose main purpose is to add an element of visual mystery and quiet humor to the ensemble.
