"Agreed." A long moment of silence as Rokuro observes the unconscious guard and his slowly beating heart. It would be simple to reach out and stop it, but...

"I... have never killed someone while they slept before. The ninja usually perform such unsavoury tasks." He would have killed the guard without a second thought when originally kneeling upon his neck, but to return and finish the job while the guard lays helpless feels different somehow. More cruel than killing him in one fell swoop.

A deep breath, swallowing down his discomfort and attempting to steeling himself for the task at hand.

"There is a first time for everything."
