Calm down there, lol. Jiraiya isn't soloing anything here.
-Boss toads are easily killed with Black lightning, since there bodies would naturally go numb as toads. Sand can be used to bury them, or Darui can simply chop off their limps. This is assuming Darui is watching and not firing Ranton's, this is assuming Gaara isn't airborne by the time Jiraiya has summoned to tailed beasts, this is assuming Gaara isn't crushing Bunta's legs with sand. Anyways, Gaara can simply generate new sand if the old sand is oil infested. Unless you are trying to imply Jiraiya is about to land a rasengan a the same moment Bunta is shooting his oil, which seems highly unlikely.
-Since when is Jiraiya in SM? Not even going to regard this point since he will never achieve SM in the first place.
-Oil +water>Gaara's sand. Oil alone doesn't canonically do much to it, so I fail to see your point
Anyways, Jiraiya will not achieve SM. Jiraiya will most likely nd up dying to Gaara's sand seeing as he has no way to escape it while also evading Darui's Ranton. His speed feats are too lacking for a match-up like this one, especially without the time to achieve SM. Team 1 mid diff.
