Transmigrated into the Honkai Impact 3rd Previous Era, but the System arrived 50,000 years early.
[Mission: Witness Kiana enroll in Chiba Academy.]
"System, let me ask you a question. What year is Kiana supposed to enroll?"
[Current Era, Year 2013.]
"And what time period am I in right now?"
[Previous Era, Year 2012.]
"Then tell me, with a 50,000-year time gap, where the hell am I supposed to find the main trio to complete this mission?!"
[Raiden Mei detected.]
Looking at Dr. MEI—whom the System had just officially authenticated as Raiden Mei—Li Mu achieved true enlightenment.
"A true expert never complains about their circumstances. If the conditions for the mission don't exist, I'll just have to create them."
"Kevin, put on this Chiba Academy girls' uniform. From today onwards, your name is Kiana."
"What 'Previous Era'? This is obviously the Current Era!"
...
Until one day, a certain God of Earth decided to skip school, using "studying history" as an excuse to visit this era for a sightseeing tour.
Only to find Schicksal, Anti-Entropy, and World Serpent engaged in a three-way standoff, while the Fire-Moth had been kicked to the curb like a stray dog.
The Thirteen Flame-Chasers were fighting side-by-side with the Thirteen Herrschers, mercilessly beating the absolute crap out of the Cocoon of Finality.
And on the moon, there was another "herself" casually inviting her over to slurp some noodles.
"Where the hell did I end up? Is this even the Previous Era anymore?"
