Depicting Mash Kyrielight in a dynamic, ready-for-battle pose, this figure captures her signature twin-tulip hair and determined gaze. She wears her characteristic blue and white outfit with silver armor accents, a gleaming breastplate, and your shield strapped to her left arm with straps and rivets. The sculpt emphasizes fluid lines in her cloak and skirt, with subtle shading on the sculpted folds to suggest movement. The base is designed to look like a stone platform with a simple emblem, giving the piece a grounded presence. The overall finish highlights glossy armor versus matte fabric for contrast.

Mash Kyrielight is introduced as a compassionate and disciplined demi-servant, a young woman bound to the Chaldean emergency service for protection and guidance. As a Shielder-class, she uses her massive shield as both defense and a symbol of her unwavering resolve to protect others, particularly the Master she serves. Her backstory ties to a lifelong search for identity and belonging, forged from a mix of human longing and divine power. Across the Fate/Grand Order narrative, Mash grows from a cautious recruit to a trusted ally whose loyalty frequently puts her in harm's way, showcasing courage, humility, and a quiet warmth.
