乃木坂 美夏

Mika is Haruka's younger sister in her second year of junior high school. Her hobbies include playing the violin, playing squash, caring for wild pigs, and spying on her sister and Yuuto. She has a personality that is the exact opposite of her sister's, who is naïve. She enjoys Yuuto's company and she often calls him "Onii-san" (an affectionate word meaning brother, brother-in-law, or a brother-like male figure). When Haruka is with Yuuto, however, Mika likes to tease them. In contrast to her airhead older sister, Mika is very stable. Even at her young age, she is more knowledgeable about sex than Haruka, although she will get shocked or stunned mentally if exposed to H-rated material just like her sister. She shows some interest in Yuuto after their date. She is deathly afraid of ghosts. She has been running for the student council president of her all girl school for two consecutive years. She is just as much as an idol as her sister at school and is known by the name Moonlight Strawberry. [Taken from Wikipedia]
