A few Captains have raised the issues of:
1. Official website being a mess.
The site in question: http://manga.honkaiimpact3.com/
AlloyBron is aware of this, and this is precisely the reason why her little helpers have set up the Mangadex site.
If the official site has problem, come to the mangadex site, or head to the Alloy Bron facebook~

2. CN and EN differences?
A number of bilingual Captains raised an issue about this.
This leads to 2 sub-questions:
a) Is AlloyBron official?
Go check the official site to find out. Basically, 1:1 copy of what you see on Mangadex.
In fact, despite Lord AlloyBron's efforts, official site admin has some architecture issues and could not be updated on a timely fashion.
Her only solution to release an English version within 24-hours of the CN release is to post on Mangadex. But that also means her little helpers work on Saturdays ><
But does that make the official site a fan-site of MangaDex? No. It's just that AlloyBron chose to post on Mangadex due to its accessibility.
In other words, AlloyBron is official.
b) Why the CN vs EN discrepancy?
The English version is designed to cater to the English-speaking audience.
Any "major" issues raised thus far were already reviewed by the official writing staff and were treated as minor issues that need no revamping.
In conclusion:
AlloyBron's Honkai 3 manga on Mangadex is as real as it gets.
And since the manga is free, as her little helpers, we're also obliged to tell you:
Play the game as well, please? The game is ALSO free.
