power rank is getting more and more illogical vuni's rarity is ur and she is a dragon race but even if mc's body ssr level is 10 levels lower than mc she must be made many times stronger than mc

Our mc got the Sss skill, which is the highest skill a person can get, but the man he fought with was an ssr, but it was made unreasonably strong, it messed up the power ranking in the story, it disrupts the flow of the story, either make the rank of mc's skill lower or adjust the power balance
