Kobato Hasegawa

As the younger sister of Kodaka Hasegawa, this middle schooler serves as the sixth member of the Neighbors Club. Driven by a deep-seated brother complex, she often acts clingy and jealous toward anyone she perceives as a rival for her brother's affection. Although she pretends to be an ancient, dark vampire named Reisys VI, her edgy persona frequently collapses into a thick Kyushu accent. Despite her shy, self-delusional facade, she remains quite popular among her classmates.
