Female protagonist version: The sword spirit girl who has been sleeping for thousands of years has finally caused harm to the world! But... Everything is broken because of this... Why do you want her sword master? Because of your good qualifications, I will reluctantly accept you as my little brother...
But...
... Damn kid, where do you put your paws? Don't touch the sword body like a lover!!! If you are not satisfied with your desires, go to your Xiaogong!!!
Male version: In your last life, you died without hesitation. In this life, I will hold on to you tightly. But the sword master discovered a truth... A happy girl is harder to push than a cold and proud girl! Asshole!
Summary: The Sword Spirit girl and her sword master pushed each other to develop a few things.
PS. The male protagonist is reborn and has a slightly sickly character.
