Meguru Hoshihara
Meguru Hoshihara is one of the main characters in the story. She is Maho's childhood friend, both having been born in the same hospital, albeit a day apart. Although she tends to act more like his "guardian" from time to time, she harbors a secret affection for Maho, getting embarrassed or flustered whenever the subject or anything related to it is brought up. Originally, Meguru did not want to become an astronaut. Her original dream was to obtain a gold medal for volleyball in the Olympics. She was also somewhat responsible for Maho's drive to reach his goal.
