Yen Press describes Rascal Does Not Dream of a Sister Venturing Out as:
After a draining December, Sakuta is quickly nearing the end of his second year of high school. Since Mai is a third-year student, they don’t have much time left together before graduation rolls around. Meanwhile, his sister, Kaede, is slowly but steadily venturing outdoors again. Just as she begins to find her footing, she announces her most ambitious goal yet—attending her brother’s high school! Sakuta knows better than anyone how difficult this will be for Kaede, and he’s ready to support her however he can. He’s just not sure if that’s what’s best for her…or what she really wants…
Returning as staff for the anime are Souichi Masui as director, Masahiro Yokotani as series composer and scriptwriter, and Satomi Tamura as character designer. Cloverworks is again the animation production company.
Meanwhile, the returning cast includes Kaito Ishikawa as Sakuta, Asami Seto as Mai Sakurajima, Yurika Kubo as Kaede, Nao Touyama as Tomoe Koga, Atsumi Tanezaki as Rio Futaba, Maaya Uchida as Nodoka Toyohama, and Inori Minase as Shoko Makinohara.
