Hikaru's been gone since for 5 years, without her friends, or the Okumura twins having any contact with her since she walked out of their lives. Now, Yukio's back in her life with memories from the past, of Rin, that she'd rather forget. As an exorcist, she was feared. Now, she's hardly active as an exorcist, fearing she'd see them again. Things have changed. Yukio wants things back to the Hikaru he once knew.
