Himawari tells a tale of love, tragedy, and sacrifice played out on two stages – Earth, and outer space. Enter Hinata Youichi, a young high school student and sole survivor of a tragic spaceplane crash that robbed him of both his family and memories roughly two years prior. Amnesiac but steady in his new life, Youichi manages to find solace in surrounding himself with friends: Amamiya Ginga, the eccentric son of a world-famous astronaut, as well as the tomboyish, yet ultimately kind-hearted quasi-childhood friend, Saionji Asuka. Everything changes, however, when an unidentified object crash-lands in Youichi’s hometown and he meets Aries, a mysterious – and similarly amnesiac – young girl from outer space. Who is Aries? What happened on that fateful day two years ago? And what secrets lurk behind the accident that turned Youichi’s life upside down?

Explore Youichi’s struggle in coming to terms with his lost memories while an entirely different story is revealed to have taken place far beyond the clouds, in the chilling void of outer space. What starts out as a young man’s light-hearted high-school adventure soon takes a more serious turn as both Youichi and the reader are led to face a sobering revelation: that not everything is as it seems at first glance.

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.”

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!”

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.
