Well Oisin,

you've got a point here.

But Sagawa-father and young Sagawa-son had the same teacher, Takeda Sokaku. Hot Sagawa-father didn't fare well, as soon as he tried his technique for real, Sagawa-son didn't have any of those problems, because he had stolen Aiki, wich made all the difference. You see, even taking the vitamins from the same source isn't a guarantee either…

Best,
Bernd
