Suigintou stands tall in a tailored black gothic-lolita dress that flows to the ground, with subtle silver trim and corseted bodice. Her long, glossy black hair cascades past her knees, framing a pale porcelain face and piercing amber eyes. A delicate black veil falls over her forehead, partially concealing a cold, determined gaze. Intricate winged accessories arch from her back, with metal-like finish and translucent accents. Her gauntlets and layered ruffles give a sense of weaponized elegance, completing the dramatic, haunted aura of this character.

Suigintou is one of the Rozen Maiden dolls created by Rozen, often portrayed as the first and most melancholic sister. She is driven by a fierce resolve to win the coveted Rose Tournament and claim the title of the perfect doll, even at the cost of others. Her heart is torn between loyalty to Rozen and a growing sense of envy and loneliness, a consequence of being forged with a brilliant but vengeful spirit. She wields power with elegance and a chilling calm, testing both allies and rivals as the story unfolds.
