Uchi no Otouto Domo ga Sumimasen Teaser Trailer Teaser visual The site also announced the anime's two lead voice cast members — Naomi Ozora (Hana Uzaki in Uzaki-chan Wants to Hang Out! ) as Ito Narita and Toshiki Masuda (Haruka Kiyomine in Oblivion Battery ) as Gen Narita. Comment from Naomi Ozora: I am truly delighted and honored to be playing the role of Ito Narita. Ito-chan is striving forward with sincere feelings in her heart, trying to get along and sometimes feeling confused as she cherishes her new family. She is a kind person who always cares about everyone around her and is filled with affection for her family. As I read the original manga, I found myself gazing at her warm heart with feelings of respect and affection. I hope to deliver to viewers the scenes of life spent with her uniquely charming younger brothers, seen through the eyes of hardworking Ito-chan. I would be truly grateful if you would watch over the animated Narita family as well! Ito Narita visuals Comment from Toshiki Masuda: I'm Toshiki Masuda, playing the role of Gen Narita in the anime. Having read the original manga, I approach each recording session hoping to convey the relationship between the two characters in the anime—sometimes comically, sometimes warmly. The brothers are truly brothers through and through — so much so that they feel like straight out of the original manga. Especially Naomi Ozora-san, who plays the role of Ito, embodies the character of Ito perfectly. You can't take your eyes off her — she's always giving it her all. Please continue to support the Narita family in the anime from here on out. Gen Narita visuals Hitoshi Namba ( Fate/Grand Order -MOONLIGHT/LOSTROOM- ) serves as director of the TV anime, along with series composition writer Megumi Shimizu, character designer Shiori Hiraiwa and Yoko Fukushima. Gin (BUSTED ROSE) provides music and Lay-duce will work on the anime production. Ozaki also shared a celebratory illustration for the anime adaptation on the anime's official X account.
