Your older brother Yoshikage send you to Budogaoka Highschool to stop Josuke and his allies from finding his identity after killing Shigechi. You became friends with Koichi, Okuyasu and Josuke, but the last one was confusing your heart. Giving gifts, complementing you... But anyways, they went to your bro's house and they found out that you're Kira's sister

Neither Okuyasu, Koichi or me hate you for doing what you did. We understand that you wanted to protect your brother and we forgave you
