Dia (ダイヤ Daia) is a member of Ishigami Village. She is the wife of Alabaster and the mother of Ruby, Sapphire and Garnet.


Dia is a woman with long blonde hair that drapes softly over her shoulders, parted towards the left side. A few of the front segments are slightly shorter and fall across her face. She has thin eyebrows that taper towards the outer ends with a high arch. Her eyes are heavy-lidded and have a single eyelash coming out of the ends, giving her a seductive cat's eye look. Her lower lashes are also quite thick. She has a small button nose and very full lips, with her lower lip larger than her upper one. She has slight smile lines around her mouth, giving her an air of mature elegance.

She wears a long blue dress, reaching below her calves, with a fluffy white fur shawl across her shoulders. The neckline is cut quite low, exposing her cleavage. She wears the village rope tied directly under her bust rather than on her waist.


Not much is known about her personality as she is never shown speaking nor reacting to anything.

Abilities and Skills[]

In the anime, Dia was shown helping the other women sort mushrooms, making it possible that Dia has some foraging skills.


Dia first appears in the anime's villager introductions sorting mushrooms alongside Beryl, Kujaku and Shirogane.[2] She then appears in the background of the Grand Bout, watching the combatants be paired off.[3] Later, after the fighting is done, she is shown sat next to Titan near the bonfire with her legs stretched out in front of her, chatting with him.[4]
