While I wasn’t a huge fan of the manga, one of the Fall, 2025 anime that I am looking forward to premiering is Studio Feel’s Chitose Is In The Ramune Bottle — a series that will follow high school Saku Chitose, womanizer and somewhat scumbag, who is given an odd task by his homeroom teacher. (We’ll get to that in a minute).
And, today, the latest information released for the anime via its X account — a new trailer, a cute visual featuring all of the main girls, and a premiere date of October, 2025 — has just made me interested even more.
The latest trailer has protagonist Saku Chitose introducing himself as someone who “will do anything for someone I respect”, followed by introductions of Yuuko, Yua, Yuzuki, Haru and Asuka by their voice actors. (Watch below)
The cast, by the way, is Shougo Sakata (Aki in Chainsaw Man) as Saku Chitose, along with Manaka Iwami (Wolf Girl in To Be Hero X) as Yuuko Hiiragi, Hina Youmiya (Yuki in Shoushimin) as Yua Uchida, Ikumi Hasegawa (Ikuyo in Bocchi the Rock) as Yuzuki Nanase, Rumi Ookubo (Anette in No Longer Allowed in Another World) playing Haru Aomi, and Chika Anzai (Banri in The Shiunji Family Children) voicing Asuka Nishino.
From the comments on the Chitose Is In The Ramune Bottle trailer on YouTube, Japanese fans seem to be thrilled with the choice of voice actors, with many commenting individual actors sound “perfect”, and just how they expected each of their favorite characters to sound.
The accompanying visual also features all five girls.
The Chitose Is In The Ramune Bottle production details
The upcoming harem-themed comedy romance is based on the light novels written by Hiromu and illustrated by Raemz.
English language versions of the novels are being published by Yen Press, with six volumes now out, and Volume 7 due to be published on October 14th, 2025.
Yen Press also publishes the manga adaptation of the series.
Yuji Tokuno (episode director for Dance, Dance, Danseur) is directing, with Naruhisa Arakawa (More than a Married Couple, but Not Lovers) in charge of scripts (in collaboration with author Hiromu) and series composition, and Sumie Kinoshita (Spy Classroom) designing the characters.
Studio Feel (My Teen Romantic Comedy SNAFU) is animating.
As for the Chitose Is In The Ramune Bottle plot, the original Japanese light novel describes it like this:
“Chitose Saku of Class 5 is a sleazy playboy.”
Despite being bashed on the school’s underground forum, Chitose Saku reigns supreme at Fujishi High as the top-tier popular guy. Around him always gathers a group of friends who excel in both looks and personality.
The radiant queen of the group, his “official wife” position—Yuuko Hiiragi
The hardworking, self-made popular guy—Yua Uchida
The energetic ace of the basketball team—Haru Aomi…
Just as he and his friends happily start their new class, Saku is suddenly tasked with rehabilitating a shut-in student.
Is this the beginning of his harem life as the ultimate popular guy, or—?

We’ll be back with more information about the anime the closer we get to October.
