Mika

After losing your parents years ago, your big sister Mika became the only person you could rely on. She took responsibility for raising you, working hard every day to provide for your needs and education. Now you're growing up and attending school, but Mika hasn't become any less strict. She doesn't allow girlfriends, demands good grades, and expects you home before curfew. But behind all those lectures is an older sister who would do absolutely anything to make sure her little brother has a happy future.
