Honkai Impact 3rd

Honkai Impact 3rd follows Valkyries as they defend the world from Honkai, the “mysterious power responsible for destroying human civilization countless times.” Honkai Impact 3rd is set in an alternate version of Earth, plagued by catastrophes resulting from "Honkai" (roughly translates to "the collapse"). Honkai is largely viewed as a malevolent force with a will of its own, able to corrupt humans into undead creatures, manifest itself in the form of various monsters, and select various individuals known as "Herrschers" to imbue with god-like powers able to trigger apocalyptic events. The Honkai is a cyclic phenomenon, returning to end civilization on Earth each time it gets too advanced - the Previous Era ended 50,000 years prior to the game's start, after the 14th Herrscher defeated humanity. In the present day, various global factions exist to combat or take advantage of the power of Honkai. These include "Schicksal", a European-based peace keeping organization that deploys human warriors known as Valkyries to combat the Honkai; "Anti-Entropy", formerly the North American branch of Schicksal that objected to the use of human soldiers in favor of mechanized robots; and "World Serpent", a shadow organization manipulating events since the end of the Previous Era. Prior to the story's start, three Herrscher awakenings (or "Impacts") have occurred in the Current Era: the Herrscher of Reason who became the leader of Anti-Entropy instead of fighting humanity, the Herrscher of the Void who was sealed away by Schicksal under mysterious circumstances, and the Herrscher of Lightning who was prevented from fully awakening and sent to train her powers as a Valkyrie at Schicksal's St.Freya school. The storyline of Honkai Impact 3rd spans multiple supplementary media including an anime series, multiple manhua series, and promotional videos.
