Chitose Is in the Ramune Bottle is an adaptation of the light novel series written by Hiromu and illustrated by raemz. Yen Press describes the books’ premise as:

Being popular isn’t easy. It’s hard to beat Saku Chitose. The most popular kid in his high school? Check. An ironclad reputation that can weather even vicious online attacks? Check. A group of friends as attractive on the outside as they are inside? Check. But when a teacher asks for his help bringing back a student who has been shut away in his room for months, Saku’s perfect world will never be the same. What is this, some kind of normie harem story…?

The light novel series debuted in 2019 and has nine main volumes as of August 2024. The books are illustrated by raemz and published under Shogakukan’s Gagaga Bunko label. There is a manga adaptation published by Square Enix.
