Valkyries are powerful female warriors that are infused with Honkai Energy by the Schicksal organization. Because Honkai Energy is extremely volatile, many valkyries are at risk of losing their lives not only in battle but within themselves as well. If a valkyrie succumbs to Honkai Energy, they will become zombies like those seen on the battlefield and will mindlessly seek to destroy humanity. Please offer these girls your full support, Captain!
For clarification, Valkyries each have multiple Battlesuits but are often referenced as Valkyries as well. For example, Kiana's battlesuits are White Comet, Valkyrie Ranger, Divine Prayer, Knight Moonbeam, and Herrscher of the Void.
