Sci-Fi (542)

Imagined technological advancements or natural settings which are currently unreal in the present day but could be invented, caused, or explained by science in the future. The narrative of science fiction (Sci-Fi or SF) stories focuses on the societal or individual reprecussions caused by the imagined technology or natural phenomenon, and are frequently dystopian in nature. Sufficient world-building is required for a work to be Sci-Fi; an alien simply visiting from outer space and living on Earth with unusual powers would be Supernatural. Characters in Sci-Fi stories can have unnatural powers without a Fantasy/Supernatural tag, but there should be a plausible scientific reason for these powers described by the creator. A futuristic setting with impossible, unexplained powers (e.g. humans randomly evolved to control the weather via thought) would be Fantasy.

Uchuu Kyoudai (Space Brothers)

Koyama, Chuuya 2024
"A big brother must always stay ahead of his younger brother. That is my responsibility as the older sibling"—these are the words that have always motivated Mutta Nanba to try his best when it came to his younger brother Hibito. So naturally, in the summer of 2006 when the Nanba brothers witness something strange in the night sky, Hibito declared that he would become an astronaut and travel to the Moon, while Mutta countered with the affirmation that he would go to Mars. That was the promise they made to each other.

Now in 2025, while Hibito is working with NASA and preparing to become the first Japanese to land on the moon, Mutta has been fired from his job in an automotive development company. Having difficulty finding another job, Mutta is given a lifetime opportunity when he receives a letter from JAXA—the Japan Aerospace Exploration Agency—telling him that he's been accepted to participate in the next astronaut selection. As if fate has given him a chance to fulfill the promise he made all those years ago, Mutta undertakes the difficult challenge of going to space.
