Amanogawa Haruka

She is a government VIP, and a part of the protagonist's family. She has always been following him. She is a third-year aerospace student at the Integrated Government Space Force Academy.

Although she is the same age as the main character, she acts like a big sister in some ways. She is one of the top students in her class, but often gets into trouble when she gets involved with the protagonist. It is always Haruka's role to persuade the teachers.

She is a dependable person who takes care of others, but doesn't make enough time to take care of herself. Despite acting like a grown-up, she just can't separate herself from the protagonist.
