All right... let me have a look here.
This is overall a pretty well-executed comic with a nice shounen manga vibe and some solid world building.
Overall the weaker areas are presentation and storytelling clarity. Like they're not terribly weak; this is still overall quite a high level piece of work, but they're the areas where if brought up a bit in quality, it'd start to really look excellent and read like a really confidently professional work.
The inks are a bit messy, which can work as a stylistic choice, but when combined with the blobby application of greys that are overall in value often a bit too dark, and how the greys are currently used less as a way to define depth and more as sort of "colouring in", it can be a little hard to read panels right now. The tone is often applied haphazardly and instead of helping the reader make out characters from backgrounds or see the depth and mass of objects and characters, they're often just adding more visual noise. Try to use your tones more deliberately to make the characters stand out and to supplement the inks. Obviously colour does tend to help with popularity on Tapas because it's a digital platform, but a very manga-feeling work like this can get away with being black and white if it looks great.
Another readability issue is that the viewpoint is always pulled in way too close and tight on the characters. There aren't really establishing shots showing scenery or where characters are in relation to each other in a room or place. It often feels a bit claustrophobic with the characters crammed into panels, often alongside a speech bubble that seems to be fighting them for space.
Pull the viewpoint out now and then! Space is really important for showing stuff like relative size, power dynamics, momentum and creating a sense of place.
Finally... Okay so a big problem I found that made this comic hard for me to get invested in was that I kind of thought the main character was a bit of a brat. I feel like the intention was for her to be bratty, but in a fun shounen manga protagonist way like Naruto, Ed Elrich or Lina Inverse, but there's an ingredient missing early on that made her never quite feel so likeable as those characters. She's not shown to have any sort of emotional vulnerability in terms of something she really cares about outside of herself (like yeah, she cares about people seeing her as a unique person in her own right rather than just a reincarnation, but she doesn't show care for anything or anyone outside of herself), but unlike a character like Lina Inverse, whose deeply selfish motivations are called out and made fun of for how over the top they are and how it draws attention to her obvious insecurity, Zessen is just consistently cocky and annoyed by everyone else, but everyone is constantly nothing but respectful towards her because of her high station.
The overall effect is that Zessen comes across ungrateful, self-involved and hard to sympathise with. Having her stuck with a duty she doesn't care about and an identity she can't relate to is good, but it'd help the audience like her a bit more if we saw what she does care about and who she'd like to be, like really hammer home exactly what her special destiny is stopping her from doing that she would really like to do; like I dunno, does she want to fall in love? Does she want to be a shopkeeper? Does she want to hang out with other young women and have fun? Something like that would really help a reader get into how her bratty, aloof attitude comes out of a sense of isolation and rebellion against not being allowed to do things we can sympathise with.
If the protagonist had a strong want that tied into the plot and decided to do things to get what she wants rather than her not seeming to care about anything and just being told to go places and going while complaining about how she has to and it's an annoyance, the overall story would have a bit more of a sense of direction.
Generally, it's not a bad comic at all, but there are areas that would really bring your work up to the really high standard I can see potential for if you focus on improving your clarity of visual storytelling and how you get across characters and narrative.
