Voice Actors:Yuki Watanabe and Maria Yamamoto
These two are Yukino's sisters. They attend the same school, and seem to know more about life than Yukino (who is older than them). As a result they tend to advise her a lot when she needs help, or just needs to vent her frustration to someone. It is these two who tell Yukino that Arima is her perfect match.

Tsukino is the second youngest in the family, she's in her third year of Junior High. Kano is the youngest, and is in her second year of junior high.
