As a newbie, being recommended Honkai Impact 3rd was great! The girls in it are all beautiful, with lovely voices and gorgeous looks. I loved the game at first sight. As a lucky newbie, I completed S-rank Seele with just one expansion and four precise pulls during the Twin Seele banner, which made me love the game even more. It should have been double the fun, and being together should have been wonderful, but why did it turn out like this? I... I've been transported to Honkai Impact 3rd and become Seele!! Not just replacing the original character, but completely parachuted in as an independent Seele! Damn it! I've never played Honkai Impact 3rd before, I have no idea about the story! Can someone tell me why Bronya looks at me like that? Who are you?! Can someone tell me why this Kiana is constantly bothering me?! Can someone tell me who Otto is?! In this dark, cold, and ruthless broken world, only that lazy module with absolutely no tutorial can bring me a little warmth.

I'm in the Honkai world, having just traveled through time. The question is, what's with this strange narration? [Take off! Take off! Such a wonderful start! Looking at this opening, you feel like your life is about to reach its peak.] No, it doesn't feel like it's taking off at all. Besides, the Honkai world is notoriously unfriendly to ordinary people, right? (╯‵□′)╯︵┻━┻. [There are many beautiful Valkyries to choose from.] [Even if you want to go big, there are Honkai Gods, Soulsteel Mini-Bishops, and Cyborgs as well.] [You feel like you're already fired up!] Not at all... Wait, Otto, you can do that? [Changkong City! The place where destiny begins! This is the perfect place for you to take your first step after traveling through time!] [Defeat the Herrscher of Thunder, then collect the Herrscher of Void and the future Herrscher of Reason into your crystal palace—the world is mine!] Wow, with this setup, you want me to go head-to-head with the Herrscher? I get it. You probably want me dead.

I initially thought this was just a typical urban fantasy novel world... drawing comics and traveling would be nice. But tell me, what's with this magician named "Emiya Kiritsugu" jumping in my face? Who changed the setting? [This book updates daily at 5 PM (5 PM).

Late-night weird show: "In Tokyo late at night, there is a grocery store that can fulfill any wish. "Its operator is evil and leads people to depravity. "Just look at it and you will fall into unspeakable madness. "The various spell props sold will devour people's hearts and plunge them into the abyss." "Now, let's conduct random interviews on the street." Interviewee - "Don't talk to me, I wasn't forced to become a stockings maid by the store manager~~" - JK·Maid·Kato Megumi---Audience (fanatical): Hurrah! Hurrah! The omniscient and omnipotent Old Ones. Women are just stumbling blocks that hinder our progress!

"Yandere," "Girl Army," "Absolute Enslavement," "Villain," "Dual Heroines," "Vampires," "Apocalypse"

The obedient girl Su Mu in ordinary days has a rebellious personality and unusual sexual orientation, like a devilish, yandere little devil.

As the apocalypse descended, Su Mu, favored by the progenitor of the vampire clan, became a vampire demon princess, gaining vampire power and the psychic talent "Absolute Slavery".

Look down on my aloof and cool female disciplinary committee chairperson? Please play some "girl games" with me under my absolute subjugation!

Note: The female lead, Su Mu, is not a saint! She might do some inhuman and crazy things! Be prepared!

(P.S.: Due to the invasion of an alien god during the apocalypse, which caused a spacetime distortion, some familiar figures from the world of anime and manga may appear in the book. Don't be afraid of DNA mix-ups! "Anime and manga appearances will not affect the reading experience~")
