Kaori is trying to join the student council and will join the student council in the next following weeks if you eliminate her peacefully.

Kaori is a preppy and graceful girl who pushes herself to act and look perfect. In doing so, she develops problems and has a hard time with self-love and confidence. One of the only things that makes her happy is her passion of makeup and hair styling, so she'll often post videos online of her tutorials. She wants to join the student council to improve her reputation further and become an even more desirable girl. 

She is Junka's childhood best friend, and she really dislikes Akatsuki.

She wants to be with Junka because she makes her feel like she doesn't have to pretend around her. If they were to enter a relationship, Junka would convince Kaori to stop worrying about what others would think and would comfort her. In effect to this, Kaori would start to act more like herself slowly and would decide to not join the student council.

Kaori attended the school along with Junka and Akatsuki when they were in middle school but moved away due to her parents' divorce. Eventually, her mother gained back custody, so she moved back to Japan with her mother and started attending the school again.

The 3rd rival in Akatsuki's mode.
