He hasn't mastered his KEKKEI GENKAI. Its a chakra limb. It can only be seen by an eye that sees the flow of chakra . I never said he mastered his KEKKEI GENKAI. Plus, he isn't even an a rank.

He never said your CHARACTER was an A-Rank... He said that the Medical Jutsu in question was an A-Rank Jutsu.

Jutsu of that level are rarely even TOUCHED by Genin, are usually only grasped and maybe learned by experienced Chuunin, and mastered only by Jounin or ANBU operatives, or those chosen to join the Shinobi Medical Corps.
