I really can't believe people still don't believe that Sarutobi-sensei and Asuma are related.

I think that the 3rd was close to becoming Hokage at the time he trained the Sannin and was highly respected, that is why they called him by his last name, Sarutobi-sensei.

Also Sandaime and Asuma...

<span style='font-size:21pt;line-height:100%'>JUST LOOK AT THE TWO OF THEM&#33;</span>

They both look a like, well as much as a 70 year old and 26-28 year old can...

I look for Asuma to be taking over the summoning chores of Enma perhaps later, or maybe another kind of monkey.

They are related, its so obvious they don&#39;t even have to state it.

They are also the ONLY TWO people to wear the Recca (Fire) Symbol on their clothing, Sandaime has it on his back and Asuma has it on his sash. Might not mean anything, but come on, lets be honest.....it might be a hint.
