You Are in Tokyo, You Have a Blood Leak, Right?

Traveling through Tokyo, Uesugiha starts out bound with the "Yōkai Illustrated Book". Precisely because of the existence of Golden Finger, Uesugiha has always believed that there are monsters in this world since he was a child. But time passed by eighteen years ago, and Uesugiha hadn't encountered a single monster. Just when his patience was about to run out and he was about to doubt himself. At the place where he worked during the holidays, a strange demon knife finally appeared. The others all stayed away, and only Uesugiha rushed forward with excitement on his face. Because he finally... Saw the long-lost red blood bar! … "Are we monsters all going to die?" Uesugiha: "?" "So many monsters died in your hands, don't you feel any guilt at all? What do you think of life?" Uesugiha: "?" "Tie Baa! Isn't the life of us monsters life?" Uesugiha said nothing and just waved the sword blindly. … As long as there is a health bar, even gods will kill you!
