About the artist

Kyoko Koizumi is credited on Pokémon TCG illustrations from 2004 to 2005, spanning 15 cards in the EX series. The bulk of this work appears in Unseen Forces, with additional cards in Team Rocket Returns and EX Trainer Kit Latios. Across these sets, Koizumi’s cards frequently center on Psychic and Darkness Pokémon, with recurring appearances by Unown.

Koizumi’s visual approach favors focused compositions and clean, minimal layouts, often built around a central subject with uncluttered framing. A playful, cartoonish sensibility and simple illustrative shapes keep the staging direct, while mysterious and whimsical moods recur through contrasting, vibrant palettes—often leaning into purples and blacks for sharper tonal separation. Dark Crobat (Team Rocket Returns) is a clear example of this character-forward clarity, pairing a tight focal point with energetic color contrast. Among the most sought-after cards illustrated by Kyoko Koizumi is Unown.
