An amnesiac young girl who fell from the sky in a vessel that looks like an escape pod. She bears the same name as one of the twelve zodiac signs. Due to her amnesia -- or perhaps her own personality -- Aries’ thoughtless remarks often leave others in a state of dumbfounded shock. Although she possesses the mysterious power to heal wounds with a mere touch, Aries herself doesn’t seem to think of it as anything special.
“The stars... are so beautiful! Look how much they are blinking!”
A girl of many secrets who keeps showing up around Youichi. She too bears the same name as one of the twelve zodiac signs. She acts in a mysterious way, alluding to certain things without revealing key details. However, it appears she knows Aries somehow...
Aqua is distant and aloof around others, unaware of the fact that her facial expression often betrays her true feelings.
“It’s because I’m a failure.”
Youichi’s classmate and childhood friend. Despite being the eldest daughter of a large and influential company’s president, the way she speaks and acts would make anyone genuinely question that fact.
Being a bit of a meddlesome worrywart, she often visits Youichi -- who lives alone -- to help him with household chores. Although Asuka views the Space Club with much disapproval, she nonetheless ends up getting repeatedly entangled in their activities.
"Couldn’t we just use my observatory instead?"
The somewhat infantile president of the Space Club. With his father being the world-famous astronaut Amamiya Daigo, Ginga too aims for the stars above.
As part of the Space Club’s activities, he’s committed to building a rocket with the goal of reaching the moon. Excelling at both academics and physical activities, Ginga possesses no weaknesses of note. His combat skills are particularly outstanding, rivaling even that of Johnny, the Saionji household’s butler.
