I left an answer to your review on chapter III. That's what I was referring to when I said I wouldn't repeat myself.

What I'm saying is that because they are from clans they have had more training than random kids entering the Academy. Also I reiterate Daisuke is the Gamer and Kimiko almost died.

I have seen Naruto. I left an answer to one of your earlier reviews so I won't repeat myself here but the reason Daisuke and Kimiko are this strong is because Kimiko is from the Senju clan, arguably the most powerful clan in Konoha, and nearly kills herself doing what she did and Daisuke is the Gamer and from the Uchiha clan, arguably the most powerful clan in Konoha.
