Contrary to Mika, Nagisa thought before acting, sometimes thinking too much that it caused trouble for unrelated or thoughtless people. Compared to other members of Tea Party, Nagisa's political capacity seems to be the highest. She likes to prepare tea leaves and sweets for tea party but Nagisa has never invited many people. Nagisa was quite calm and calm, but like everyone else, she also had her limit and could become quite cruel when someone made her lose her temper.
