Fumika Kodama  

Fumi, Fumi-chan, Katie, Katie Forrester, 木霊 文花

Fumika is a person who possesses kindness and playfulness. Her popularity often results in her being considered cute with an attractive charm. When under the influence of yokai, she maintains her cheerful disposition but may come across as unintentionally cruel. Despite this, she does not recall these incidents. Fumika is intelligent but also has concerns about meeting her mother's expectations. She displays surprising bravery and comfort with heights. In the anime, Fumika serves as Keita's love interest. Although Keita consistently tries to impress her, his efforts appear to be in vain. Additionally, Fumika frequently experiences possession by yokai, prompting Keita to confront them on her behalf.
