^This is non-sense. For starters you don't have any proof about whether Hashirama has Slug Summoning or not. Either Hashirama learnt it from the Clan Elders or It was from Myoboku who have been guiding heroes from the dawn of this Ninja World. Also Katsuyu is actually younger than even the Two Grand Sage Ma and Paa. Nor does she seem to possess any capability of yielding Sage Mode or Even teaching especially considering how Shikkotsu Forest has only one summon.
