"The Sinful Tree?"
Yaku perked up, took the nutrition injection the girl passed to him, and stuck it into the infusion port on his arm.
Given his identity, he should not have accepted an untraceable nutrition injection, but what was imperative at that moment was to regain his strength. The appellation made him recall the creature, resembling a tree, he had encountered in the sewers. If it had already been there for a while, then the situation could be much more serious than he had imagined.
"That's the name I gave it, and it exists somewhere in the sewers."
The girl said, "You came from above, so you must have heard about the disappearances of people in The First Region, right?"
Several years earlier, the rate of disappearances in The First Region had been among the highest within the United Government, surpassing even most border cities with extremely high crime rates.
