Kaoruko

カオルコ

Kaoruko is the older twin, characterized by a pessimistic nature and a lack of self-esteem and confidence. She is not outgoing at all and barely talks to people. During the double date, her sister stays at Doumeki's side while Kaoruko spends most of her time talking to Watanuki but keeps her sight on Doumeki. Despite Watanuki encouraging her to have a positive attitude, which would allow her to have more confidence in herself, Sakurako does the contrary and causes her sister to revert to her original attitude. This is why she ends up being a customer in Yuuko's Shop. She has an infatuation (crush) on Shizuka Doumeki.
