Honkai: Star Rail: Kiana's Lost It, Stop Streaming, It's All Embarrassing History!

In 2016, at St. Freya Academy, just as Kiana was worrying about her Valkyrie exam, a livestream arrived that would change everyone's fate. The world of Honkai: Star Rail, the Previous Era, and other places were all pulled into it. Bai E: Why is the Amphoreus recap playing backward? This thing called the Iron Tomb can wipe out the whole universe in a second? No way! Wait, what do you mean I'm inside the Iron Tomb's body too? Sparkle: Once you get to the Planarcadia, call me Sparxie. Who are you calling flat-chested? I'm cute or cool, can do offense or defense. Do you even understand the value of changing size whenever and wherever you want? Stelle: I heard you could become an Aeon in the Planarcadia, so I came. Where do I claim my perks? Otto: Wait, Luocha, so you went after the Ambrosial Arbor too? March 7th: I said I wanted seven days off a week, and Sunday said I could have anything in my dreams. I didn't expect him to actually put me in a dream! That's so mean! Dahlia: You got what you asked for, and now you're complaining. Gopher Wood: I told you, Sunday would never lie. Sa: The Kiana Emperor challenged me to a duel, then crossed the solar system and killed me in one hit? How am I supposed to fight that? Kiana: Here's the problem: how did I actually become the Herrscher of the End?
