The series is scheduled to premiere on July 4 at 12:00 a.m. on Tokyo MX, Gunma TV, Tochigi TV, BS11, and other stations, running for two consecutive cours. Voice actors Daisuke Ono and Aya Endou join the cast as Isao Narita and Saho Narita, respectively. The opening theme \"Aikotoba\" is performed by the band DISH//, while singer-songwriter Reira Ushio performs the ending theme \"Clover.\" Both songs are previewed in the new promo. Hitoshi Nanba directs the series at studio Lay-duce, with Megumi Shimizu handling series composition, Shiori Hiraiwa designing characters, and Gin composing the music. The manga began serialization in Shueisha's Bessatsu Margaret in January 2020, and its 14th volume was published in July last year, with the 15th volume due June 25.","whyItMatters":"The two-cour premiere and the involvement of established music acts DISH// and Reira Ushio suggest the production committee is positioning this shoujo comedy for a sustained broadcast run rather than a single-season test.","webCardHtml":"\u003cp\u003eThe additional cast announcement fills out the Narita family tree: Daisuke Ono voices Isao Narita and Aya Endou voices Saho Narita, both new characters not previously listed in the main sibling lineup. The core cast had already been announced in March, including Naomi Ozora as protagonist Ito Narita, Toshiki Masuda as Gen, Kensho Ono as Syu, Taku Yashiro as Raku, and Momoka Terasawa as Rui. A key visual and an earlier trailer were released at AnimeJapan 2026. The production credits at Lay-duce include character designer Yoko Fukushima alongside Shiori Hiraiwa, a detail one source notes while another does not. The manga's 15th volume is set for release on June 25, just ahead of the July 4 anime premiere, a timing that aligns the print and screen launches.\u003c/p\u003e","blueskyPost":"DISH// and Reira Ushio, both from current-season shows, take the theme songs.
