Meet the Ribon Couple Behind Bandai’s Honey Lemon Soda Keychain

Kai and Uka Mini Rubber Keychains from Honey Lemon Soda by Bandai

The Shojo Manga That Captured a Generation of Ribon Readers

Honey Lemon Soda is a high school romantic comedy by Mayu Murata, serialized in Ribon — one of Japan’s most storied shojo manga magazines, published by Shueisha. Ribon has been shaping girls’ manga since 1955, having introduced readers to series including Chibi Maruko-chan and Sailor Moon over the decades. In the early 2020s, Honey Lemon Soda became one of the magazine’s headline titles, running for roughly fifteen volumes before concluding around 2023.

The story follows Ishimori Uka, a shy and withdrawn high school student whose world gradually opens up through her relationship with Miura Kai — a classmate defined by spiky blond hair and the classic tsundere dynamic: outwardly blunt, inwardly caring. The series received a live-action film adaptation in Japan in 2021, and a television anime followed, likely around 2024, which is typically when Bandai-produced character goods of this kind see their broadest release. The franchise has also reached readers abroad through English-language manga publishing, giving Honey Lemon Soda an audience well beyond Japan.

Two Characters in Chibi Rubber Form

This item is a mini rubber keychain in the chibi style — characters modeled with oversized heads, simplified expressions, and compact proportions, a format deeply familiar to anyone who has browsed Japanese anime goods. The material is soft PVC, sold attached to a ball chain suitable for clipping onto a bag or displaying on a shelf. Both characters come together in a single set, packaged in a clear polybag.

Uka is rendered in her school uniform: white shirt, yellow vest, red ribbon, and a red-and-blue check skirt, with dark hair and the wide-eyed look the chibi format naturally amplifies. Kai wears a white short-sleeve shirt with a blue-stripe necktie, his spiky blond hair remaining immediately recognizable even at this small scale. The visual contrast between the two — dark hair against blond, quiet against confident — carries over effectively into the chibi format and reflects the central dynamic of the series.

One small note on the listing title: “Ishimori” is Uka’s family name. Kai’s surname is Miura, not Ishimori. The title shorthand combines the two characters’ names in a slightly simplified form rather than listing both surnames separately.

Where This Kind of Goods Fits in Japanese Anime Culture

Rubber keychains are among the most recognizable and widely produced character goods in Japan, typically manufactured to coincide with an anime’s broadcast run. They circulate primarily through anime specialty retailers, franchise storefronts, and events such as Anime Japan — not through general retail, which means they remain largely within the domestic Japanese market. For fans outside Japan, this category of goods has historically required proxy services or forwarding addresses to obtain directly.

Bandai, the manufacturer, is recognized internationally through its work on franchises including Gundam, Dragon Ball, and Pretty Cure, which gives buyers a reliable frame of reference for the production quality of its character goods. For shojo manga or anime fans who have followed Uka and Kai through the manga volumes or the television series, a set that pairs both leads together offers a self-contained way to bring the central relationship of the story into a small, portable object.
