I hate to point to some of these things. I should be cutting Kishi some slack but then I can sometimes be pedantic.
1. I just read chapter 599 so i don't know whether you guys have already tackled this. In page 11 the hokage monument includes that of Minnato even though Minnato couldn't have or had been hokage.
2. Kakashi is supposed to have completed the academy at age 5, a chunin at age 6 and Jounin at 13, right? So the question is why is it that in this chapter Kakashi is taking part in the chunin exam at about age 10 or 11 with Rin and Obito. Why would he even be part of a team of genins.
look at the pic they look younger than ten or
eleven they look the same age as naruto did at his
