Oh, then that makes much more sense. Oro and Kabuto are still enough for her. Old Hiruzen isn’t stronger than both kage. He was getting beat up by Hashirama once Mokuton started coming into play, Jukai Kotan along with Oro and Kabutos active assault while Bringer of Darkness is active is too much for her to handle.Tbh. I don't know if OP for #2 means the sound 5. Probably the sound genin.
If that's the case I don't see her losing because she's > old Hiruzen by pt.1 feats. And old Hiruzen > pt.1 restricted edo hokages.
She could literally just smash her way through to Orochimaru and end him imo.
But yeah if it's all the sound ninja in general Tayuya's Sound Genjutsu shits, coupled with the others help like Sakon/Ukon body merge. Yeah she loses.
