## Description
The story takes place in year 2050 and centers on Youichi Hinata, a high-
school student who lost his parents in a tragic accident. Constantly hanging
out with his close, yet eccentric buddy, Ginga Amamiya, the two of them are
working on a project to make a rocket and launch it all the way to the moon.
Foolish task for the kids, but they’re serious about it in their own way. One
peaceful night, while Youichi was on the phone with his childhood friend,
Asuka, talking about the stars, he noticed a falling star. Not thinking too
much of it at the time, after the phone call he noticed there was something
different about it. It wasn’t a falling star… it was something else, and it
fell down nearby. He went out in the dead of night to try to locate the fallen
object. On his way there, he run into Ginga and the two of them approached the
park where instead of a fallen meteor, they saw a small spaceship. Not sure
what sort of alien they might encounter, or if it’s even alive, they opened
the hatch only to see a dazed girl in place of a pilot. Seeing how Youichi is
living alone, and until they figure out what to do next, they decide that
Youichi should take her in for the time being. And thus the story of Youichi
and Aries begins.
The story is presented in two different timelines. The present time in 2050,
and two years prior the accident, in 2048. The game contains all the expected
gameplay features to be found in a visual novel, such as message log with
ability to skip to previous scenes or replay dialogues, quicksave and
quickload options as we as regular save option with up to 99 slots, the
ability to remove the text to see the clear background picture, and bonus
galleries and music player. The PSP port main differences in comparison to the
original release is that it has full voice-acting for non-player characters,
additional episode that extends the story, and many new CG events making this
port contain three times the original.

chapters and were integrated in a single all-chapter releases. In 2015, the
