Giving mei SS rank is a bit of exaggeration. From the army of 10k only around 500 were competent ninjas most of them were canon fodder slave genins, chunins, some jonins who died due to chakra exhaustion and were boiled or they didn't have any sensor ninja to sense mei who used silent killing to kill them And a single berserker s rank who is as idiotic and hothead as hidan. Kitsuha killed himself with his own jutsu. The rest of more than 9000 of the forces were mercenaries with no chakra. Its only due to the idiocy of her enemy and the mc saving her from from the first attack of the second in command of kitsuha that she won. Even the naruto from the start of Shippuden could have killed the mercenary army and the ninjas aside from kitsuha himself with shadow clones and 1 tail chakra cloak and he was only as strong as low jonin despite having chakra reserve surpassing kage level by a lot and he didn't receive the training mei received nor did he have any army killer bloodline to use. Rant out and I am sorry if someone didn't like my thoughts.
