Wait a second.
Kido is a top tier Root member. So he should be one of the strongest Shinobis in Konoha besides the Kage tier guys. That makes him 7-B+ if not 7-A. Which is fine.
But he's presumably just a normal human. No special bloodlines or anything. Just exceptionally skilled and rich
What's more interesting is the Tailed Beast Drug. Which is made by harvesting Naruto's leftover DNA in the Valley of the End along with "body of a a descendant of Hagoromo Otsutsuki" (could easily mean any of the random dead Uzumakis/Senjus/Uchihas lmao). When Kido consumed one of these things, he apparently becomes ONE THOUSAND TIMES STRONGER. His jutsus (the bear trap ration) also became one thousand times faster.
This is a normal, if exceptionally skilled, human, eating a Tailed Beast Drug that logically shouldn't give power anywhere near that of an actual Bijuu. It's made of leftover Naruto and corpse DNA. As far as we know, it doesn't contain any actual Bijuu Chakra. It's mass produced for crying out loud.
Actual Jinchurikis are often the absolute top tier Shinobis of their village (they have to be to survive) AND they have actual Bijuus sealed in them. With Bee's V2 Bijuu state being directly stated to have the power of a Bijuu in a human body. Logically this should someone like V2 Bee, who has direct cooperation with Eight Tails and has full access to his powers, would out scale TBD Kido by an extreme margin. Who is a "normal" Anbu/Root guy and is using a drug that "replicates" Bijuu power.
And for strength it does. TBD Kido going by multipliers would be in the 6-C+ to baseline High 6-C range. But speed is another matter. Going of our current ratings, Kido would blitz V2 Bee by an absurd margin. Literally 28x faster. This doesn't make any sense. Am I missing something?
