t first, Tsukasa appears to act very cool, calm and level-headed; seemingly unsurprised by Nasa's rash and illogical actions. Despite this, she agreed to marry Nasa and does love him very dearly. As they get to know each other, she starts to display more emotions than simply acting calm; she gets embarrassed very easily whenever Nasa proclaims his love for her and how cute she is. Tsukasa also seems to get jealous at times, like when Nasa talked about how cute Aya was. While she acts indifferent towards Chitose (despite her family taking her in), she does end up developing an understanding relationship with Kaname Arisugawa.
