Mikleo didn't hesitate to grab Sesshoumaru's arm the minute he spotted the demon choking the poor human. Sure he was a terrible detective and damn straight he should have been killed but Mikleo's morals didn't allow that. No one deserved to die even if the were truly messed up and full of crap. The shorter boy's hands increasingly tightened his grip when he grabbed Sesshoumaru's arm.

"Hey let him go. This isn't how we're suppose to do this."

He replies calmly. Please don't make him have to reprimand a God, Sesshoumaru. He's a Shinki and he will overstep his boundaries.
