Minato namikaze, can't he be naruto's uncle?. Until someone in the manga don't mention Minato namikaze like Uzumaki's Kushina, then we can't say that he is naruto's father, but at least we knows Yondaime Hokage name. Now we need to know who is the heck is Kazama Arashi which is the name next to Jiraiya's name and before naruto's name in the summoning scroll.
If Naruto is Yondaime's son, then I just don't get why they treated Sandaime's grandsom with a lot of respect and love whille they treated naruto like trash. I just don't get it.
