Saori

Saori (沙織 Saori) is an anime-only character who appeared only in First Stage and was Itsuki Takeuchi's first love interest. She breaks up with him after being involved in a car accident caused by Shingo Shoji, who mistook Itsuki's Eight-Five for Takumi Fujiwara's Eight-Six. Itsuki negligently engaged in a downhill battle with Shingo while Saori (still in the vehicle) pleaded with him to stop. The reason for the breakup was that if she stayed with Itsuki, her memories of the accident would come back to haunt her, so it would be better to break it off completely.
