cattleya (queen's blade)
Cattleya (カトレア) is a Queen's Blade character. Voiced by Yuzuki Ryouka, designed by Kaneko Hiraku. She is a blacksmith, weapons store owner and a former adventurer with huge breasts. She has black hair tied into a ponytail, blue eyes, and glasses. Fights with swords and spears. She entered the Queen's Blade tournament to find her missing husband. Has a young son named Rana.
Rather unusually, Cattleya is one of, if not, the most popular character of the franchise, despite it featuring wide array of casts for general appeal. Primarily due to her volpulous and motherly appearance (to the point that one of her Pixiv tag is "120cm", referring to the official measurement of her huge breasts). Which lead into her being featured in numerous MILF works.
