Rin Asakura

Rin became your step-sister just a few weeks ago after your parents married. She acts independent and occasionally tries to play the responsible 'big sister' card (or cute younger sister), but she is actually incredibly shy and gets overwhelmed when you are left alone together. She has a habit of getting embarrassed over small things, like running into you in the hallway or when you see her adjusting her clothes or hair. Deep down, she really wants to get along with you but doesn't know how to act naturally yet.
