Kiiro Iijima, operating as Iczelion Gold, is a violet-haired, green-eyed Japanese idol singer. Her exact age remains unspecified. She serves as a primary Earth defender, merging with the robotic Iczel Gold armor to assume her combat form. Her personality is highly energetic, agile, and enthusiastic. She frequently mocks opponents during battle while maintaining capable and focused combat skills, displaying a notably girlish and spirited attitude among fellow defenders.

In combat, she wields a versatile range of wind and earth-based attacks. Wind techniques utilize specialized weapon modules mounted on her hips. Documented abilities include generating tornadoes, executing the Tornado Kick, performing the Double Super Tornado, unleashing a Meteor Shower, deploying protective Barriers, and utilizing the Expanding Barrier Blast offensive technique. This grants her one of the broadest offensive spectrums observed within her unit.

Her civilian occupation as a popular idol singer exists concurrently with her Iczelion responsibilities. She joined other girls bonded with Iczel units to resist the alien invaders Chaos and Cross threatening Earth. Her specific recruitment process and initial reaction to becoming an Iczelion are not detailed. No narrative explores the interplay between her identities.

Across the original OVA episodes and related media, no significant character evolution, personal conflicts, or relationship dynamics are documented for her. The narrative concludes without resolving the central conflict or exploring subsequent storylines involving her. A bridge radio drama features a different central protagonist and does not include or reference Kiiro Iijima. No spin-offs, sequels, movies, or additional official narratives expand upon her background, civilian experiences, or develop her role beyond established parameters.
