Premieres July 2024. This visual was done by the illustrator for the light novel series that the show is based on and is commemorating the AnimeJapan 2024 convention coming up near the end of March. Check out the ANN article for more information on cast/staff. Synopsis from AniList:
Koi wa Futago de Warikirenai, written by Shinon Takamura, follows a boy named Jun as he falls in love with the twin girls who are his childhood friends and live next door; both of which who couldn’t be more different from each other. Rumi, the older sister, who has a boyish exterior but a maiden-like personality while Naori is super girly and also a super otaku.
Sorry to say that from what I have read of the story so far, no yuri on the horizon in this one. It would take on a whole other set of tags in that case.
