A second-year student and Literary Club president from the prestigious Nase family. She's a Spirit World Warrior—basically someone who deals with supernatural stuff—and she's best known for her blunt way of talking. People often mistake her directness for sadism, but she's shown genuine compassion more than once.
Her official reason for hanging around Akihito is to keep tabs on him, but honestly, she worries about him constantly. They're close enough that she can speak to him without any real filter, which works in their favor since they actually get along pretty well.
