One can guess that this Japanese woman, Tanaka Yoshiko, is not a saint.
Even Zhu Fan is afraid of her, so the power behind her is not trivial. Xiaofan still remembers what happened at the training base. Zhu Fan was very respectful to the man named Kawashima Jun, not just because of his strength. Given the current power Zhu Fan wields, he shouldn't need to be so respectful to anyone; the only explanation is that Kawashima's status is much higher than his.
The Red Butterfly organization has been destroyed many times; it has quite a history spanning years. The assassination order once placed on Ren Zhongtian reached two billion US dollars, which is enough to show their fear of him. Ren Zhongtian indeed wiped out Red Butterfly several times.
The previous Five Ghosts apparently had dealt with Ren Zhongtian before, and the resurrected Red Butterfly means they got a new boss while their backers never gave up.
