Can I point out that your MC seems suuuuper OP?

I mean... four unique Kekkai Genkai? Jonin at age 9? Isn't that ridiculously difficult to do?

Though with Nardo's power creep later in the story I guess that could kinda justify it, but still.

It's still an awful lot of kekkai genkai. I mean, don't most characters have say 1 or 2 kekkai genkai at max? Having four means your OC probably *s away a good chunk of the other, more normal characters.
