Gemi has been credited on Pokémon Trading Card Game cards since 2023, with artwork appearing through 2025. Their credits are concentrated in the Scarlet & Violet series, including 151 and Scarlet & Violet, with additional work appearing in Crown Zenith Galarian Gallery.
Across these cards, Gemi’s approach is primarily digital illustration, often using vibrant palettes with cool and aquatic leanings. Compositions tend toward balanced layouts with occasional dynamic staging, supporting scenes that read as playful, serene, and cheerful. A recurring clarity of foreground focus and clean silhouettes complements the colorful, lightly whimsical tone. Among the most sought-after cards illustrated by Gemi is Glaceon VSTAR.
