Mizuho Kazami

Disguised as a high school teacher, this 23-year-old inhabitant of the Galaxy Federation serves as an undercover observer on Earth. Despite her human lineage, she possesses a fragmented personality and remains largely ignorant of terrestrial culture, save for her intense passion for Japanese sweets. Her arrival brings unexpected complications for her neighbor, Kei, especially as her sister, Maho, frequently targets him with lethal intentions. Alongside her mother, she remains a mysterious presence navigating her new planetary home.
