Why Do You Hold a Sword? to Protect My Oath!

I once had a sword... That could cut through the sky. But it can't cut through the chains of disease, it can't cut through people's words, it can't cut through... This fate that makes people miserable. This sword... Is returned to heaven and earth. If there is an afterlife, I will definitely find you again and take you to see the most beautiful meteor shower in the world...
