Actually this brings up something I've always wondered.
We all know that multiple ninjas are just cannon fodder, but what happens to the survivors as the others die? Like, let's say you kill 9 of these ninjas, does the one remaining get ALL of the ninjutsu, thus becoming a unstoppable silent killing machine, or does he still only have 1/10 of the present ninjutsu, relegating him to an embarrassing kata before being offed with a dismissive one-liner?

Somebody needs to test this.
There's a webcomic called order of the stick that joked about that. A paladin fought off a horde of ninja, with the last one yelling that he was unstoppable now.
He got crushed by a cleric-turned-giant next panel.
Also, dr. Mcninja had an arc about this. The villain had exploited this rule by going one man army against all the clans. Turns out conservation of ninjutsu(among other things) is one of the laws of physics in their universe.
