Kokoro Shinguuji

Reina's class president. She has a strong sense of justice and doesn't hesitate to stand up against problematic behavior, even against Reina's antics, which initially puts them at odds. However, they make peace after it turns out they're both capable of seeing ghosts and other paranormal entities. For unknown reasons, she unwillingly attracts evil spirits to herself, often suffering the consequences of their influence.

She's also excellent at time management and organizational matters, going as far as accidentally intimidating a tour guide with her knowledge and detailed schedule during a school trip abroad.

At times, she exhibits a strong maternal instinct towards others, for example obsessing over getting Reina to start eating vegetables as if she were a child.
