"The Senju Clan's enormous Chakra isn't so easily disrupted!"
Minato Namikaze remarked with a sigh, as if lamenting how difficult life was for civilian ninja.

But there were exceptions. When the Chakra reserves of the caster and the target differed enormously, the target could use their overwhelming Chakra to exhaust the caster's Chakra. Affecting a ninja with only one unit of Chakra and affecting one with a hundred units required entirely different amounts of Chakra.
"Sakura, you've become much stronger than you were at the Academy."
