When the yakuza achieves the next rank themselves, i.e. goes from thug to gang boss, they gain the signature location permanently and may therefore teach it to another.
reiella said:Hmm, so even when you advance past or equal to one of your teachers, you're still part of their dojo structure? So, let's say just for example, if Hanoi Xan got up to Oyuban before Meowth (Theoritical), he'd still be part of Team Rocket's gang structure?
