oh, i thought it was called baku.
well, i guess neji and darui win mid-high diff like above. this would come down to a battle of attrition and how long it takes darui and neji to figure out izanagi and counter it.
darui and neji are two of the best level-headed, smart minds in NV, and i doubt it would take long for the two of the combined to figure out that danzo's izanagi lasts for one minute per eye, and that he has eleven lives until he runs out. neji's stamina is relatively unknown, as we have seen practically zero feats from him since part 1.
however, daruis vast stamina and chakra reserves are unquestionable, shown when he fought the army of white zetsu at the coast, then immediately fought, figured out, and defeated kinkaku and ginkaku, also having easily used three of the legendary tools that drained tenten's entire chakra in a single use. between the two of them, darui and neji have the necessary stamina and feats to go at an all-out slugfest with 11 danzos.
danzos relatively straightforward wind-style attacks like vacuum bullets and fuuton shuriken are countered by neji's kaiten and 360 degree vision, which make for an excellent defense. on offense, darui's laser circus, water wall, gale style, black panther, and decent kenjutsu feats are enough to repeatedly overpower danzo, granted he is without KA and his summon.
