Episode 1 is scheduled to go live around 3:00 p.m. on that day. The project is a new character IP based on the Matsuken Samba persona of actor Ken Matsudaira, who voices the protagonist Matsuken. Sumire Uesaka plays Matsuinu, Matsuken's canine partner who uses a keen sense of smell to find the causes of people's frustrations and sometimes delivers sharp retorts. Daisuke Namikawa voices various other characters, including office workers, bosses, store clerks, and friends. Kayac Akiba Studio Inc. participates as a production committee member and handles character creation and overall animation production. The short anime follows Matsuken and Matsuinu as they brightly punish the frustrations lurking in modern daily life. Cast comments from all three voice actors were released alongside the announcement, with Matsudaira noting his surprise that a character based on him would become an anime. The company says the project may expand into merchandising, events, and promotions.","whyItMatters":"This is a character IP built from scratch around a real performer's existing public persona, with the actor voicing a fictionalized version of himself in a YouTube-first format rather than a traditional broadcast.","webCardHtml":"\u003cp\u003eKayac Akiba Studio Inc., the production committee member handling character creation and overall animation production, confirmed the date on the project\u0026#39;s official X account on August 21, 2026, announcing \u0026#34;We have kept you all waiting!
