Hitagi Senjougahara

戦場ヶ原ひたぎ

Hitagi is a frail girl with an "incurable disease" who became weightless after an encounter with a mysterious crab, leading her to isolate herself and threaten anyone who discovers her secret. Initially, she presents herself as a tsundere, speaking abusively and rarely engaging with others. However, after developing feelings for Koyomi and overcoming her trauma, she transforms into a more cheerful and normal girl, using cute nicknames and emojis while still retaining her sharp tongue. She also hints at having an Electra Complex, leaving the sincerity of her admission ambiguous.
