Review Detail of JackalVadim in NARUTO, Kushina's Brother

I like how the story develops. Usually when a main character becomes too powerful by age 3 (Jonin level or something) it's off-putting, but here it makes sense that he became a seal master at that age (and the desire, and the backstory, and the adult mind, everything leads to this). In other aspects of further development, the main thing is to try not to go too far. A kid who can beat up a kage seems funny. (But the choice of how to develop the story is yours, the author. I'm not asking you to change your story, that's just my opinion). Thanks for your hard work.
