[Honkai Impact 3rd] Is This Difficulty Still Honkai Impact 3rd?

One day, a girl appeared in Siberia.

She calls herself Bai Qi Kaslana. She has the exact same face as Kiana and is a genius among geniuses. She's also like a treasure trove: whatever you want, she's got it. There's nothing she can't get, only things you haven't thought of.

At first, I thought this would just be an ordinary Honkai Impact 3rd playthrough. But who could have expected the world to expand into Honkai tides, swarms of Honkai Beasts, and the Eighteenth Herrscher...

Tell me, is this still Honkai Impact 3rd?
