Glossy Ruby is a Jewel-attributed Dressia from the Data Carddass Aikatsu Planet! arcade game series, first appearing in Part 1. It made a cameo in Episode 01 ("Suddenly an Idol") of the hybrid live-action/anime series before its official debut in Episode 02 ("An Idol After All☆").

This Dressia appears humanoid with ruby red eyes and hair. It wears a ruby-and-gold crown with an attached veil and a small velvet cape fastened by a ruby pendant. Its primary attire is a long gradient red dress, existing in two documented versions:
- **Version 1:** Features a ruffled red dress with a mauve gradient skirt, sequined ruby fabric around the chest, and gold ornamentation set with rubies. Accessories include a pearl choker, silver bracelet, red nail polish, and mauve sandals with ruby-adorned red straps.
- **Version 2:** Consists of a maroon two-piece outfit: a single-shoulder strap top and a gradient skirt embellished with gems. Accessories are mesh gloves with gold bracelets, a ruby choker, and red peek-toe heels with gold anklets.

In gameplay, Glossy Ruby is associated with Swing Cards of varying rarities and skills. A Level 8 Premium Rare card activates a "Climax Battle Level +1" skill when facing opponent Dressia exceeding level 8. A Level 4 Rare card provides "Main Battle Level +1" against Rare-rarity opponents.
