If you had impeccable nature energy control you could have tiny amounts of chakra and still use Sage Mode. Lorenzo.r.1st wrote: hagoromo (in the filler) sensed it without gama telling him that it was there at all People have to be taught to sense it, but we don't know if Toad Oil is the only way to sense it. Juugo's KKG suggests that other means exist. So it's possible that people can learn to sense it in other ways. I doubt he was naturally able to sense it.
