Despite being a creation of Kaguya, he was inwardly against his inventors' philosophy, and instead followed the ideology of his Chakra Relative,, and learnt. Since he had the chakra of both his Chakra Relatives residing within him, he was able to quickly learn how to utilize Ninshū effectively, eventually making secret techniques unique to him and a clan he would eventually form.

Kaguya was highly angered upon the realization of the fact that Kouwa had access to the Eishagan, and thereby had the potential to gain Sensory skills greater than her own, and Kouwa eventually did become much more powerful than his inventor, not only in sensory skills, but also in power. After his inventor was sealed away, a recessive effect took place, and Kouwa was placed in a deep sleep, waking only after the disastrous had ended.

Background
Kaguya had struggled for ages, trying to create a new invention that would serve her with all of its heart. After utilizing a combination of both Hagaromo and Hamura's chakra, Kaguya had invented a new potential servant, Kouwa. Kouwa struggled to be accepted by his Chakra Relatives, whom he considered actual siblings. Kaguya, on the other hand, accepted Kouwa for who he was, and the only clash between the two was that the two did not want to follow each others' philosophy.
