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.

Shin Megami Tensei Devil Children

Fujii, Hideaki 2024
Ever since his mother passed away, first-year student Setsuna Kai swore to become stronger for her sake. Despite tireless daily training at his elementary school's kendo club, he still cannot defeat his rival and friend Mirai Kaname. However, on their everyday walk home from practice, an ominous black haze appears over Tokyo, blocking out the sky and plunging low temperatures, covering the city with crystal snow in the middle of summer.

As Setsuna returns to his dark apartment, a child flies through the walls and hands him a wrapped box before taking his last breath in his arms. A demon, hellbent on taking his life, appears before Setsuna can process what had just occurred. At death's door, Setsuna's conviction to live awakens a power from deep within him, allowing him to summon a demon of his own.

The Cerberus demon named Cool explains to Setsuna that he is one of the eight Devil Children who fought Hell and must now fight to save the world from destruction. Though he is vehemently opposed to accepting such an important responsibility, Setsuna's determination to surpass Mirai drives him to assume the position. Alongside Mirai—who also happens to be one of the fated Devil Children—Setsuna dives into the Demon World to locate the other six in order to fulfill their mission.

Somewhere in Vladivostok, Russia, a deal has been successfully completed. Danger looms over the horizon; a deadly virus—capable of killing within three hours of infection—has now fallen into the hands of a mysterious woman named Maya.

Enter Fujimaru Takagi, a seemingly ordinary student at Mishiro Academy in Japan. However, very few know that he was famed for exposing crimes and corruption of high-profile individuals with his brilliant hacking powers—the infamous "Falcon" who had abruptly vanished from the cyberworld. Only the members of Third-I, a top-secret division of the Public Security Intelligence Agency led by Fujimaru's father Ryunosuke Takagi, and his friend Otoya Kujou know of his past.

When a KGB agent is murdered in Japan, the only clue to his death is a memory chip found at the scene of the crime. Fujimaru is recruited by Third-I to decode the chip, which contains a video file of an event called the "Christmas Massacre." Investigating the incident further, Fujimaru's father uncovers more information about the homicide and a mysterious code, "Bloody Monday," before being framed for the murder of his superior. Now, it is up to the hacker Fujimaru to utilize his expertise to help Third-I prevent the spread of terror and destruction in Japan, while attempting to clear his father's name.

Ginga Eiyuu Densetsu (Legend of the Galactic Heroes)

Tanaka, YoshikiKatou, NaoyukiK 2024
In the far future, two young military leaders rise above their peers. The invincible genius Reinhard von Lohengramm is matched only by the unbeatable magician Yang Wen-li; though the two share a profound respect for each other, they meet on the battlefield not as comrades but as bitter adversaries. Commanding thousands of warships and millions of soldiers, they lead giant space fleets into battle on behalf of the two interstellar states that have wrested for control of the Milky Way for over a century and a half.

The Galactic Empire, an absolute monarchy ruled by Kaiser Friedrich von Goldenbaum IV and an entrenched nobility, seeks to suppress the rebels daring to oppose the inviolable crown. The Free Planets Alliance, a representative democracy led by a corrupt High Council, degenerates as its elected leaders⁠ use war and conflict as a way to win popular support. Reinhard is a minor noble who became a High Admiral through his strategic brilliance and his sister's position as the favored concubine of the Kaiser, while Yang is an avid historian and reluctant commodore hailed as a hero despite only using his tactical prowess to navigate around his leaders' incompetence. On opposite sides of the galaxy, the two men have wildly different visions for the future: Reinhard dreams of uniting mankind under his iron fist, while Yang wants only to carve a path to lasting peace. As the war rages on, Reinhard and Yang each strive for their ideals and secure their place among the stars as the leaders of a new era of galactic heroes.

In an alternate history of the aftermath of World War II, Japan has been cleaved in half, with the south—Honshu and the other islands—allied with the United States and the northern island Hokkaido annexed by the enigmatic Union. It was on Hokkaido that a mysterious tower had been built, a strand of metal reaching up out of the atmosphere, visible from the northern tip of Honshu. In 1996, three teenagers, Hiroki, Takuya and Sayuri, make a pact—they will build an experimental aircraft, almost invisible to surveillance, cross over to Hokkaido and unlock the secrets of the tower. Their dream was never realized, because Sayuri was sent to Tokyo for treatment after she fell into a coma. It is now three years later. The rosy illusions of youth have fallen away, but not the unbreakable strength of the trio’s promise. The truth of the tower will be uncovered, and with it, the link between it and Sayuri’s mysterious, carefully tended condition.
