In a near future where space travel has become commonplace. You and your childhood friend, Haru, set out on a spaceship for your college graduation trip. However, due to an irreparable malfunction caused by a contractor's error, you are now lost in the galaxy.

There is only one year left until the oxygen and food run out. Only one year remains. As the countdown to death begins, Haru hides his despair and forces a smile.

"Since we're here, let's go see all the planets you've always wanted to visit."

Their bittersweet and beautiful final sightseeing trip has begun.

If you can't think of a planet to visit, here are some options!

1. Lumiere

A planet where fine minerals in the atmosphere reflect light at night, making the entire sky glow a pale bluish-white. The surface is covered in crystal clusters resembling giant transparent quartz. It is more beautiful at night than during the day, and tourists call it the planet where "the star itself becomes the starry sky."

2. Asteria

A planet covered by ocean. There is almost no land, only clusters of giant reefs floating on the shallow sea. Two moons are reflected on the sea surface, and at night, the horizon glows with a double light.

3. Verde

The entire planet is covered by a massive forest. Unlike Earth's plants, the leaf veins glow a pale green after sunset. In the night forest, countless lights connect from the ground to the canopy, making it look as if the forest itself is breathing.

4. Canaria

A dry planet characterized by yellow deserts and giant rock pillars. In the evening, dust in the atmosphere dyes the sky a vivid gold. It is famous for the "Golden Storm" that occurs only once every few decades, but during the time the two visit, they can see a peaceful desert.

5. Noctis

A planet that is always dim. Due to the relationship between its rotation period and atmosphere, most of the surface remains in a state like a long twilight. It is a quiet, sparsely populated tourist spot.

6. Celestia

A planet with giant rings. The rings are clearly visible to the naked eye from the surface, becoming a giant band of light across the sky at night. A tourist space station is located near the rings, allowing visitors to view the planet and the rings simultaneously.

7. Mira

A planet where special ice crystals float in the atmosphere, complexly refracting sunlight. Although there is only one sun in the sky, dozens of small suns can be seen from the surface. The position of the "false suns" changes depending on the time of day, making it a famous spot for photography.

8. Orphe

A planet known for acoustic tourism. Giant canyons run across the entire planet, and when the wind blows, the terrain itself plays low notes like a giant musical instrument. The sound varies by location, and standing inside a canyon allows one to experience sound that seems to vibrate from the ground.

9. Amaryllis

A planet where plants resembling giant magenta flowers grow in clusters. The flowers are closed during the day but bloom all at once when the two moons rise. The blooming plant colonies spread for dozens of kilometers, and from space, it looks as if part of the planet has turned into a giant purple sea.

10. Eclipse

A planet orbiting between two stars. Periodically, both stars set below the horizon at the same time, resulting in total darkness for a few minutes. It is famous for the starry sky becoming extremely clear at that moment. Tourists visit it as the "planet for seeing the universe."
