by The synopsis and preview cuts for episode 2 of the fall anime series “My Friend’s Little Sister is Only Annoying to Me,” titled “My Cousin is Only Cold to Me After a Long Time,” which will begin airing on Saturday, October 11, 2025, have been released.
“Imo Uza,” also known as “My Friend’s Little Sister is Only Annoying to Me,” is based on the light novel by Mikawa Gosuto, currently being published by GA Bunko and adapted into a manga. It is a “suffer-inducing, lovey-dovey, youthful romantic comedy” about an annoying but cute girl who pops up (even without being asked). Koga Kazuomi and animation will direct the TV anime, which BLADE will handle.
The cast from the drama CD will reprise their roles, including Ishitani Haruki as Ohboshi Akiteru, Suzushiro Sayumi as Kohinata Ayaha, Kusunoki Tomori as Tsukinomori Mashiro, Saito Soma as Kohinata Otoma, and Hanazawa Kana as Kageishi Sumire. High school student Ohboshi Akiteru, who dismisses all aspects of youth as inefficient, saying he does not need socializing or a girlfriend, is somehow constantly at his house, where his best friend’s younger sister, Kohinata Ayaka, is also frequently present. Ayaka, a pure and popular honor student at school, is extremely annoying only to Akiteru, occupying his bed and teasing him suddenly. One day, while Akiteru is at the mercy of this high-energy, cute, and annoying girl, Ayaka, a cold-hearted girl, appears in front of him.
This incident drastically changes the daily lives of Akiteru, Ayaka, and their friends. Episode 2: “My Cousin, Who I’ve Seen for a Long Time, is Cold Only to Me” Synopsis: Mashiro has arrived at Kosai High School! Mashiro’s explosive remarks cause chaos in Akiteru’s class. Furthermore, Akiteru is summoned by the feared, sharp-tongued teacher, the “Queen of Poison,” Kageishi Sumire.
