Tsugaru Santamaria is presented in a vibrant Busou Shinki MMS style, standing approximately 150 mm tall in a striking red and white armored suit. The figure features glossy armor plates with gold trim and subtle weathering, faux fur accents at the collar and hem, and a flowing cape that adds a sense of motion. Her helmet-like headgear carries a festive aesthetic with crisp lines and metallic highlights. The included EX Weapon Set Santa Claus complements the look with chrome and red finials that echo holiday motifs. Moveable joints allow dynamic posing, and the set includes display-friendly accessories for a dynamic shelf presentation.

In the wider Busou Shinki universe, Tsugaru Santamaria is portrayed as an elite MMS unit forged for winter campaigns and festive defense. Forged in a cold workshop and infused with a hint of holiday spirit, she patrols snow-blanketed battlegrounds where rogue machines threaten cheer and order. Her pact with the Santa Claus-themed EX arsenal reflects her role as a guardian of merriment, delivering precise, non-lethal disabling strikes while boosting allies with rallying energy. Legends tell of her relentless discipline, clever tactics, and a compassionate core that turns every skirmish into a chance to protect towns, friends, and the season's joy.
