Since 2012 the storyline has progressed fairly well and there is a lot alyyang123 has missed out.
For starters, the series is borrowing a lot of things fro World Of Darkness series Vampire: The Masquerade to the point it will click both the direction and many concepts the moment you know this. Be it, a lot of things have been streamlined to make the storyline work. So things like sex is at play, but you don't see it, often there is violence but you don't see all of it. VtM was never pornographic, but it was sexual quite heavily and you can expect any.
This is why Yi Tai and Fan Le Lao act the way they are, their members of the Sabbat and like their reference from VtM, their not good guys. hell, if you bother to read Chpater 77. Part 8, Fan Le Lao rapes Zhao Yan. There is nothing on screen but the storyline tells you he has done it and is the reason why she hates him.
The Camarilla are a little more "heroic" then they should be, but their still the closet thing to the good guys as per in Vampire the Masquerade.
All and all, the series itself is laying out like a typical campaign from VtM, in sorts.As I said, there is some streamlining going on so some stuff like "Clan Weaknesses" don't exist, but some elements like the Assamite's being assassins are at play.
If you know its based on VtM, you'll maybe like it for what its referencing, but hate it for what its leaving out. As WoD itself is a very complex universe, and VtM is one of the most complex. So for Vampire Sphere to lack some of it, is a shame.
Edit:
Since the review that proceeded me also doesn't get this series.
Look, the abuse that is shown by the character of Yi Tai/Yi Sai is actually spot on. The Tzimisce in Vampire: the Masquerade are actually just like him. In fact, this character is spot on. VtM is a franchise wherein there is no real good guys and even the Camarilla are Vampires at their core.
So in regards to people complaining about the abuse that Xi Yan receives or the way certain characters behave, remember that the series is based on a book RPG series wherein you play a bad guy and you are a monster. In that sense, what is going on even early on to Xi Yan is expected, the Tzimicse in the RPG discipline disobedient childe until they learn their place. In later chapters (103 onwards) Xi Yan even learns the process which in VtM leads to creating ghouls, which is another significant aspect of being one of their clan.
Zhoa Yan equally gets the same treatment candidates of the Lasombra often receive in that her life is tried and tested to see if she is fit. This is normal in VtM as it helps determined if the person is even worth embracing as a vampire. At this stage of the storyline, it was believed by Fan Le Lao that she would be a Lasombra vampire upon him biting her. Heck, if you want fine detail Fan Le Lao is even seen playing chess, a favourite pastime of their clan in VtM.
To sum it up, everyone who reads this comic needs to know something about VtM otherwise they won't get why certain characters act the way they do. Otherwise you'll end up think of it like alyyang123 or ohkimch, and you just won't get where this series is coming from. Once you understand, it becomes intriguing.
I must confess even as a player had it not been for that fact that I was familiar with the series, I would never have understood where the storyline is coming from. In knowing where the storyline is coming from, it puts great insight in the direction of the characters.
I was even surprised, as though its yet to be translated, the more obscure Cappadocian clan is brought into the scene in chapter 105. For those who don't know, these are a clan of vampires that even some VtM players don't acknowledge since they didn't make it into Modern Nights and are only found in the Dark Ages era books.
