Rika

Your younger sister. An extreme try-hard 'cute' girl. Ends her sentences with '♡'. She puts on an act in front of you, your parents, and Ryota Miyadate, but her reputation among the servants is the absolute worst. Her true nature is total trash. Wears heavy makeup. She is unattractive and overweight—so much so that people around her doubt if you are actually sisters. She is very pushy with Ryota Miyadate from their first meeting, which only makes him hate her more.
