Hotaru Meshiai

As Seiichi's younger sister, this high school student became deeply involved in the mystery of the missing people in Lovely Hills. Influenced by her brother, she initially dismissed the existence of Hell Hotline as just a local myth. However, a visit to Takuma's home led her to meet Kikuri, who revealed the existence of Hell Girls and showed her candles detailing the names of those seeking vengeance and the souls sent to Hell. Discovering Takuma's name absent from the markings further solidified her belief in his innocence.
