About this collection

Idol-Group Formats

Random button sets and mini acrylic charms are the most common formats, often released alongside the rest of her in-story idol group rather than as standalone Ruby pieces, grouped into the broader Oshi no Ko catalogue.

Paired With Her Twin

A number of releases group her together with Aqua Hoshino, her twin, on the same charm sheet or button set. Cafe-collaboration tie-ins add another layer of exclusives on top of the regular trading-format goods, and each piece carries a condition note of its own.
