The fourth season of the anime series "Iya na Kao sare nagara Opantsu Misete Moraitai R" (colloquially "Iyapan") will begin streaming on April 30, 2026. Coinciding with the premiere date, the first episode synopsis and pre-released scene stills have been revealed.
The first episode is titled "Chitose Ito (Head Maid), Nanako Mita (Clumsy Maid)". It focuses on two maids: Chitose Ito, who is known from previous seasons and has repeatedly shown her panties with a disgusted look, and the new, clumsy maid Nanako Mita, who makes her debut in this fourth season. The plot begins when the inexperienced Nanako breaks a plate belonging to the master of the house. The caring head maid Chitose wants to take responsibility for her colleague—but then, as is typical for the series, things take a turn: both lift their skirts with a grim look. The first stills show precisely those scenes where Chitose and Nanako present their underwear to the audience in a disgusted manner.
The original series "Iya na Kao sare nagara Opantsu Misete Moraitai" is based on a concept by the doujin artist 40hara (Shimahara) from the circle Animal Machine, who developed it into an illustration collection. The recurring scenario: various beautiful women let the viewer see their panties under a scornful gaze.
The fourth season will be streamed every Thursday at 22:00 (JST) starting April 30, 2026, on d Anime Store, AnimeFesta, Niconico Channel, and other platforms.
