The final chapter of Miyuki Nakayama's manga Spirits & Cat Ears was published in the August issue of Kadokawa's Comic Cune on Friday. Kadokawa will release the final volumes, 12 and 13, simultaneously at the end of the year. Spirits & Cat Ears began in January 2014 in Kadokawa's Monthly Comic Alive and moved to Monthly Comic Cune in November 2017. The series has been collected in 11 Japanese volumes, the most recent shipped in June 2022. Yen Press publishes the English edition and released the 11th volume in September 2023. Yen Press also published the fourth volume of Blend-S on March 24, 2024. The manga follows Neneko Iizuna, a character with cat ears who becomes a miko tasked with exorcising spirits in an infirmary. Yen Press describes the story as focusing on her interactions with new coworkers. The series inspired two drama CDs. In March 2025, the announcement of the sixth compiled volume included plans for an anime adaptation titled Ore to Yu Nii! The manga is available on digital platforms such as Manga UP!, ebookjapan, LINE Manga, and Kindle Store. Kadokawa intends to publish the concluding volumes before the year ends, concluding a twelve‑year run in Japanese manga magazines.
