Their job was thus: To track down a rogue mage by the name of Jeb Silk who had been raiding the laconic, prosperous town of River Village. The dark mage had a talent for shadow magic, and used the cover of darkness to slip into the town and steal from the coffers. The inhabitants of River Village had reached out to Dies Irae, posting a blacklist notice so that guild wizards would take care of this threat for them. It was unknown if the thief was affiliated with a dark guild or not, but part of Dies Irae's mission was to protect the citizens of Earthland, and Jeb Silk was destabilizing the economy of this village. If left unchecked, the amount of havoc he would cause could grow to enormous proportions. So, Kenzo and Illya had taken the contract to capture the rogue wizard, dead or alive, and present him to the village headman to dispense justice.
With that in mind, Kenzo glanced down at his belt, ensuring that the leather case that held a pair of magic-dampening handcuffs was still fastened to it. The reward was the same whether or not Silk lived, but Kenzo intended to capture him alive. To kill him would be to allow him to escape justice, and that was something the Demon Slayer could not abide.
"You know the plan, right?" he said, turning to his companion, assuming she'd caught up to him. Their plan was to lie in wait on the outskirts of the village in the dead of night, using Illya's exceptional sense of hearing to detect when Silk approached, then ambush him. Kenzo had come up with the plan. He didn't wish to disparage Illya, whose unending enthusiasm brought a sense of light-heartedness to everything she did, but sometimes that same carefree nature could get in the way of mission planning. Thus, Kenzo, to whom such planning was more or less old hat, had taken the lead, despite Illya holding a higher rank than him.
