The art is great, and the characters aren't bad, but the plot? It's so weak. Every time you spot a plot hole, the next chapter will have the main character monologuing something like, "Oh, actually, that rule doesn't matter because /insert random explanation here/"... It feels like they're constantly making up new stuff without properly explaining important details about her character. She seems like she knows what she's doing, but in reality, she has no idea, especially when it comes to her relationships with other characters (and her disciples!)
That said, I really enjoyed the arc about the three fathers and their sons, it was so wholesome.
