ミルファリア・ウル・ウルリラ

The Big Breast Maiden who was made to become Haruto’s ”Personal Boobs” by order of the breast deities. She is traveling with Haruto. 

She may be the Maiden who worships the Big Breast Deity, but she believes in the teachings of the days before the continent was split: that there is no reason to discriminate based on breast size. 

She has a cheerful, soft-hearted personality, can’t even imagine doubting a soul, and gives her all to whatever she does. 

Because she’s descended from a long line of Big Breast Maidens, she produces milk when she becomes sexually aroused. Haruto squeezes her boobs every day, but she tries her best not to let it out.
