only asura's descendant/reincarnated have perfect sage mode without any fault/ Body Modifications
Hashirama
Naruto
not descendant/reincarnated of asura
Kabuto with Body Modifications
Imperfected Sage Mode
Jiraiya
not sure about minato but
Minato
senjutsu is not his strong point, as it takes him too long to gather
natural energy and he can't maintain it for very long
Jūgo isnt list as sage mode user
Despite Jūgo being a user of Sage Transformation,
none of his techniques are listed as senjutsu in the fourth databook
so we only 2 perfect sage mode user|(without any fault/ Body Modifications ) Hashirama & Naruto both are descendant/reincarnated of asura
