That's plot.kamui is overrated and it has weakness like when minato whoop obito butt
or when konan blow obito up but he won using a cheat move Iznagai
i will say the Limpo is the strongest
alot of wanking on kamui though
And having both let's you rustle the entire nv.Kamui. Even having only one eye puts you on kage lvl.
Just like that Code Geass eye.Kotoamatsukami. This technique is practically like Edo Tensei. You command someone who can't even know it.
