Tetsu no Sosuke let out a soft breath, temporarily set aside the jumble of thoughts in his head, and took the letter from inside his clothes to read it by the surrounding firelight.
The conditions were less than ideal, and Tetsu no Sosuke had to concentrate a little to make out the words.
After reading the entire letter, he rubbed his chin and glanced at the two members of the Hidden again.
The letter clearly laid out the information on both men.
Strictly speaking, these two were not actually members of the Demon Slayer Corps.
Although they wore the Hidden's uniforms and seemed to play the part well enough, they had actually joined the Demon Slayer Corps less than a month ago.
And their backgrounds were deeply unsavory!
Just as Tetsu no Sosuke had sensed, these two really did have some psychological problems.
And their twisted minds had already led them down the wrong path as human beings.
Both of them had originally been sentenced to death.
But just before their executions, Ubuyashiki Kagaya had saved them.
For the time being, he needed men like them to test whether they could make vicious demons cough up information.
The letter instructed Tetsu no Sosuke to remain here throughout this period.
For one thing, something unexpected might happen, and Tetsu no Sosuke needed to be here to respond.
For another, he was to keep watch over these two men.
If they tried to escape, he could carry out the executions that had been left unfinished.
Once these two slipped out of their control, they might prove no less dangerous than demons... so he was to show no mercy!
And even if everything ultimately went smoothly and they really did obtain information through methods such as "torture," these two were still to die.
