Even though both Patriarch Muto and Patriarch Kiri had already reached the Fake God Realm, for some reason they still felt inferiors towards Patriarch Senbu.
Perhaps it was their lifelong beliefs and thoughts that had made them somehow subservient to the Senbu Clan, always awaiting their decision.
Perhaps it was a natural fear of facing someone dangerous, like their natural enemy. Just like little mice in front of the house cat.
Of course, neither of the two would accept or admit to something like that. First it would dampen their spirits, and second it would fully destroy their image and achievements.
As for Patriarch Senbu, he was just looking at the two old fogies in front of him with an extremely careful and startled look.
He had already created an idea of their strength by looking at their fight from afar but now that he had them in front of himself, he could finally determine that they had reached that 'Realm'.
