@ThrowingHands Kakashi didn't say in the exact words that he "derived the Chidori from the Rasengan", but said something similar. It is justified say it's like a parent-child relationship, at least for Kakashi's case. He said he couldn't add a nature to his Rasengan so he created the Chidori. How are you not getting, that the existence of the Chidori was due to Kakashi. It might not be in a perfect circle, but is related. I really don't know how to explain it to you clearer.
