Then hire someone who does! This is not a valid defense for this
Unless someone like say, Sony, swoops in to take control of the KS's management, it's way too late for that already.
Firing Awesome Japan is one thing.
Hiring someone capable to immediately take control of it, the coordination, planning, etc. All of these are time-consuming things on its own, never mind hurdles like negotiation with another marketing agency and other potential issues.
If this was a 60-day KS, there might be a chance for that. But with only 20 or so days left, kicking out A.Japan will do more bad than good, because clearly Ys Net don't have the skills to manage it on their own.
<- Worked in marketing in project coordination and management. Trust me, this shit is WAY, WAY more complicated than it sounds.
