Protecting from a distance does sound like a plausible idea, eventually Mizuki may discover him, but remember that I'm basing this Character off of the Assassin Creed games and there are missions where you must protect someone in transit. Sometimes you take the the rooftops and attack from above sometimes you simply start a fight out in the open and that motivates the person your protecting to move a little faster. Assassins don't have to be invisible to do there job, they simply have to be forgettable enough to the right people.<br/><br/>For now I will go with the 'guardian angel' directive and stay out of sight, hell if your posting the quest me you can make that part of the mission.
