The protagonist's younger sister. With the birth of their long-awaited daughter, the sibling parents' flower garden was in full bloom, and they elaborately named her after it. However, it was only after the birth certificate was submitted that they realized that the phonetic pronunciation of the name was "Baka", as in "Stupid". She's innocent and very positive, but perhaps because of her name, she's also an idiot who doesn't think about anything, prancing around completely naked at home with no sense of shame in her bones. She has no sexual knowledge whatsoever, but gradually learns to take pleasure in the act of "studying" with her older brother, the protagonist. She is glad that there is something that she can do, even though she is an idiot, and begins to actively seek out the deeds. "Wow! Onii-chan can produce milk from his penis!" [Edited from DLsite]

主人公の年の離れた妹。 待望の娘の誕生で頭の中の花畑が満開になった両親が凝りに凝って命名したものの、音読みにすると “バカ” になることに気付いたのは出生届を出した後。 天真爛漫で非常にポジティブだが、名前のせいか何も考えていないバカ。 自宅では基本的に全裸で、羞恥心などまったく無い。 性的な知識も一切無いが、主人公との “勉強” という名の行為の中で、次第に快楽を覚えていく。 そしてバカな自分にも出来ることがあって嬉しいと、積極的に行為を求めるようになっていく。 「すごーい！　お兄ちゃんはおちんちんからミルクが出せるんだー！」
