Byakugou no Jutsu isn't sage mode. I never said that. I said it works just like Sage Mode. According to the databook it increase your overall abilities and stats (just like SM does) but it also comes with a regeneration factor (not healing).
And I agree Toads and Snakes are more diverse.
While I agree with you Byuakugou allowed Sakura to replicate Rokudo level ability. Sakura was able to rezist the effects of a double rinnegan SM JJ Madara's TSB rokudo rods, regenerate and continue her attack. A feat yet to be matched by anybody with either sm or greater up to incarnate Rinnegan Sasuke. He touched and removed lesser rods but could likely remove/resist Rokudo rods.
I said sage mode
if we ever see it then I will retract my statement
You're obviously suffering from delusion 3 are mentioned as
Sage regions and
2 Sage regions have sage mode. What do you think the
3rd Sage region has? Or why it's referred to as one of the
3 Sage regions?
As Lamasander Uchiha provided there are 3 Sage regions.
In Naruto universe Sage is title that represents beings that can harness natural energy and enter Sage mode.
Sage title is given to those 3 regions .
Apart from those 3 there is only 2 times in manga when sage title is given :
1) Hagoromo and we know he was sage mode user.
2) Another time sage title is used is with 4 tails Son Goku who is reffered as " King of sage monkeys " but kanji used with Son Goku is completely different from those 4 mentioned so its not official Sage title but just regular sage ( wise man ).
Kanji used for those 3 regions means actual Sage ( that can harness nature energy) not sage as wise man, so there is in fact Sage mode related to Slugs.
