Even if you don't like Ianthe Tridentarius, you gotta hand her one thing:
She is so unapologetic in her bullshit. No doubt, no remorse, no hesiatiton. She took one look at the trials, she saw people die and she went "Yeah, I get that you died but I'm built different". She stepped up to fight a Lyctor with nothing but Babs' half eaten soul and the power of audacity. She performed a lobotomy on a traumatized nun and the only question she asked was "what is your price range?". She was so ready to open a can of whoopass on Camilla, the fact that she failed does not negate the fact that she is a cringe girlfailure who really thought she was cool there.
Her situationship? More like dictatorship. With who? The resurrected ex of the girl she tried to date. Her boss? God. We know that she is as pleasant to look at as a H. R. Giger painting. She tried the " and there was only one bed" method on Harrow and it didn't work. She is in love with her literal sister but acts comically disgusted towards necro-cavalier relationships (Knowing her sister wants to be her cavalier...) like she is morally superior.
She is one of the characters of all time.
