Animate has unveiled Harajuku Himegoto House, a multimedia project spanning television anime, music, and additional media. According to the announcement, the narrative is a "high-tempo gag" story about an aspiring hitman who travels to a rumored assassin hideout in Harajuku, only to find a cafe operated by a group of eccentric, high-fashion individuals. The project's production and planning are managed by Plott, while Bandai Namco Music Live (Lantis) oversees the music and Animate handles promotion. Original character illustrations were drafted by visual artist Aki Akane. The voice cast includes Yūya Hirose as Mizuki Otokozawa, Tetsuei Sumiya as Mero Togariishi, Sōhei Horikane as Takara Rokurokusō, Masaru Yoshimura as Kentarō Jinbayama, Takuma Nagatsuka as Yuki Inubo, Nobuhiko Okamoto as Hitoshi Haritsukekawara, and Showtaro Morikubo as Shō Dogenzaka.
