Osananajimi to wa LoveCom ni Naranai Anime Casts Sae Hiratsuka

Hiratsuka to voice Runa Tsukimi in 2026 anime

The official website for the television anime of Shinya Misu's Osananajimi to wa LoveCom ni Naranai (I'll Never Have a Romantic Comedy with My Childhood Friend) manga presented on Tuesday a new teaser visual featuring the character Runa Tsukimi, and also announced that Sae Hiratsuka will voice the character. This is Hiratsuka's first role in a tradittional romantic comedy.

Runa Tsukimi is an "angelic or devilish little sister"-type girl who suddenly started living with Eiyū and expresses her attraction towards him more upfront than anyone else. She is one of four heroines in this story.

The manga centers on Eiyū, a high school boy whose two childhood friends, Shio and Akari, also go to the same school as him. He has now started looking at them with both romantic and lustful eyes, though he knows that they have no interest in him, which causes him no end of worrying. However, Shio and Akari have their own secrets.

The previously announced cast members are:

• Rin Kusumi as Shio Minamo

• Yū Serizawa as Akari Hiodoshi

CyberAgent is producing, and Tezuka Productions is animating the project.

The anime will premiere in 2026.

Misu launched the manga in Kodansha's Magazine Pocket website in March 2022. Kodansha published the manga's 17th compiled book volume on Tuesday.
