Some Bujinkan guy in Greece (renting his training space from Kostas`and his students, that means teaching BBT in the Pammachon school in Athens) accused Kostas on a greek forum openly that what Kostas teaches now is nothing else than his own version of the Bujinkan.
That much I seem to understand. What I do not understand is why Kostas chose to try to drag Hatsumi and his accusation against him into the conversation.
If this was between Kostas and the other guy, then he should not have tried to cover himself by bringing in the matter of the Bujinkan and his thoughts about Hatsumi.
