so ig it's similar to losing your body but your soul is still live and can see... terrifying. She was tortured so much only to become a spirit that follows wherever the sword goes, so everytime someone kills a person with the sword she sees it first hand which can probably literally destroy someone's psyche + the fact she was also there to witness the torture and the killings of her family... this continued for 400 years... it's quite horrifying and i feel sad for our protag,, go get your revenge!
