maybe but i don't think so cz in the beginning she thought that her father didn't like her but he said that he loved her as his daughter and why would you give your daughter a knife if you loved her and other than that why a beautiful one at fact so i think he knew that the knife does time traveling and gave her and bc if i didn't like her i would give her an old knife or something bc i would never dirty my beautiful knife on a waste of time that i didn't like either so i think that the knife was the reason why she went back in time and the father knew what was gonna happen and set that up so that she could survive but i'm also kinda confused i now i maybe think that your explination could also be tru but idk....
At chap 27, there is one panel from the Dad's POV that said "I know the ending of this story" with a picture of a hands covered in blood and a sword. So I just want to ask, Does her father know the past?? Or it's just an error in translation and uploading the photos? (⊙…⊙ )
