Kagome Higurashi shooting Naraku with a single arrow, pissed off at him for exploiting Sango's for her brother into stealing Inuyasha's Tessaiga for him, then manipulating her brother Kohaku into almost killing Sango... which is enough to have her use said arrow to purify the heavily poisoned air in her surroundings and blast half of Naraku's body off.
Naraku: You are... Kikyou's... reincarnation...?
Kagome: (to Naraku) Naraku, you are totally despicable. Now, DIE!
Kagome: (to Naraku, same scene) I won't let you go, even if you BEG for forgiveness!
