That sounds good. I'm sorry if that spoils some things you had planned but you can still play their initiaal time together as very early in their relationship - as I will be doing with Urbaanzorro, my slaave will be learning her limits as she goes along, so the fun 'training' part gets done at the same time as the master and slave become involved in the wider story.<br/><br/>One thing Ryuuji should change when he takes Mizuki to the BAF office is the geographic boundary that set on her collar. She will have been given an 'open' boundary while travelling from England to Nice and Monaco, but now she is here, Ryuuji should restrict it to just the area he thinks she needs to be allowed to roam within ;)<br/><br/>I am thinking the system is much like cell phone coverage from various masts, but these would be smaller and more discrete and sit on building rooftops. Each would give a coverage signal to just a hundred meters or so and each will have a coded signal and ID number, so when a BAF official draws a boundary on his interactive map-screen with a digital pen, the codes of those masts within the boundary are loaded into the collar memory as safe and all mast IDs outside that boundary are coded as hostile. In rural areas the masts would be planted far further apart with wider areas for each and so coverage would be coarser grained but still effective.
