Firefly is a custom keycap kit designed around Firefly, a character from Honkai: Star Rail, capturing the dynamic contrast of her signature warm and cool tones.
The palette centers on a warm white as its dominant base, grounded by a muted brownish-gray that gives the set visual weight. A soft teal green appears prominently across the set, balanced against a vivid amber orange and a deeper teal that anchors the cooler tones. Novelty designs by Seo_bun bring the character's aesthetic into the finer details.
Firefly is produced in Cherry profile using PBT keycaps with dye-sublimated legends.
