Monsters known as "Horrors" have invaded the world, entering through gates from the Makai Realm of Darkness. These corrupt, demonic creatures have the ability to seize human bodies and feed on their souls. Citizens who are out past sunset will likely never see the sun rise again, but those who live in the capital city have no need to worry—they are protected by a spiritual force field created by the sorcerer group Onmyouji. In possession of legendary armor, the Golden Knight Raikou proclaims that he will protect everyone from the Horrors. Accompanied by his attendant Kintoki and the mysterious Makai Alchemist Seimei, he strives to become a formidable Makai Knight, but Raikou is ill-prepared to handle the side effects of the armor. Disappointed by his own shortcomings, he sets out on a journey of self-discovery to master his weaknesses and prove his worth. [Written by MAL Rewrite]

Episodes 14–16 of OreImo 2 which finish adapting the OreImo novels.

The United Earth Sphere Alliance is a powerful military organization that has ruled over Earth and space colonies with an iron fist for several decades. When the colonies proclaimed their opposition to this, their leader was assassinated. Now, in the year After Colony 195, bitter colonial rebels have launched "Operation Meteor," sending five powerful mobile suits to Earth for vengeance. Built out of virtually indestructible material called Gundanium Alloy, these "Gundams" begin an assault against the Alliance and its sub organization OZ. One Gundam, whose pilot has taken the name of the slain colony leader Heero Yuy, is forced to make a crash landing into the ocean after an atmospheric battle against OZ's ace pilot Zechs Marquise. Upon coming ashore, he is found by Relena Peacecraft, daughter of a peace-seeking politician, who witnesses Heero's descent to Earth. Although neither of them realize it yet, this encounter will have a profound impact on both their lives, as well as those on Earth and in space colonies. [Written by MAL Rewrite]

In 2019, a rift to another dimension suddenly opens in the skies above, revealing a "turnabout" alternate world called "Shinkoku Nippon." This parallel version of Japan maintained its militarism and remains stuck in the Showa era. Shinkoku Nippon invades our Japan with its "Genmu" gas weapons and giant humanoid "Garan" weapons. The invaders immediately take over our government and all but conquer Japan. As a result, our Japan never ushers in the Reiwa era. A decade later, our Japan has been revamped as Genkoku Nippon, a puppet state of Shinkoku Nippon. Under harsh censorship, the once thriving manga, anime, idol, and similar sub-cultures have completely died off...or so it seemed.
