七瀬 桃花

Brotherly term of endearment: "Onii-chan"

The daughter of Souichirou and Aya. She’s unaware of just how much she spoils her brother. With their parents gone on vacation, she’s taken up all the housework herself.

Her talent for cooking is fairly remarkable, particularly her specialty in baking sweets. 
Momoka is devoted to her beloved family, and has a kind, often motherly personality. 
While she may look like she has everything together, she can’t keep that facade up at all times, especially when it comes to her weakness for sugary foods, leaving her constantly self-conscious about her waistline.

She tries to restrain herself for the sake of the other sisters, but, like them, she’s been in love with her brother from a young age.
