Aria

Aria is a key character in the anime The Sacred Blacksmith (Seiken no Blacksmith). She is the Demon Sword of Wind (also called the Demon Blade of Wind), a powerful demonic weapon born from a demon contract during the ancient Valbanill War.

In her true form, she appears as a rapier, but she has the unique ability to transform into a beautiful young woman. In human form, she's depicted as light-hearted, flirtatious, romantic, very feminine, cheerful, and always in good spirits. She has long brown hair, yellow eyes, and a mature yet playful personality. She's also a big eater with a huge appetite.

Her past involves being used in wars for killing and destruction, which has left her with a resigned acceptance of her nature as a weapon of violence. However, she forms a close, affectionate bond with Cecily Campbell (the knight who wields her), showing fascination with Cecily's reluctance to kill and developing a strong friendship with her. Aria often displays a teasing or affectionate side toward Cecily.

(She's voiced by Megumi Toyoguchi in Japanese and Anastasia Muñoz in English.)
