They both have good chances of winning against each other. Sound genjutsu can one shot itachi while amaterasu can one shot jiraya. 55/45 in favor of itachi, i'd say. And as for susano, jiraya sinks that shit as well as toads can come in handy.
Totsuka and Yata mirror powered susanoo? Totsuka would literally slice apart all of Jiraiya's summons and amaterasu would 1 shot Jiraiya
Yata blocks attacks. I never stated jiraya breaks through. I said he sinks it while a toad sits of it to ease the sinking process. As for totsuka, it doesn't have much of speed feats. May be it seals one toad with surprise element but then other toads will avoid it. Plus if itachi has to fight toads with techs like susano or amaterasu then he is done for. As those techs have dangerous backlash which can be exploited. And sure amaterasu can one shot jiraya as i stated myself of jiraya isn't careful but clone spam can save jiraya a few times as it did against pain. And sound genjutsu also one shots itachi. Still i gave it to itachi 55/45.
Itachi if jaraiya can't access safe mode
Otherwise, sage mode rapes
-Sound genjutsu
itachi dies of chakra exhaustion after 30 min of fighting. with jiraiyas diverse jutsu arsenal that he seems to launch in quick succesion itachi would be forced into susano pretty early on if nit right off the bat. once in susano i give itachi maybe 10-15 min before he's useless.
my guess is jiraiya knows what the yata and totsuka are seeing as he's well traveled and knows alot about the naruto world and those 2 weapons are legendary.
so toad oil plus fire jutsu creates a big enough aoe attack to force itachi into susano and from there its a battle of attrition that jiraiya is most likely to win unless he gets genjutsued before summoning the chiefs to do sm
once susanoo comes out itachi violates him
Jiraiya get mid-diffed lol what can he do against the MS?
Jiraiya faps need to log off. Itachi amaterasu him with or without sagemode. People need to let go of the frog gen too because he only pulled that off by hiding from pain.
It literally solos but k
