"The Two… Darkness and Light" (二人…闇と光, Futari… Yami to Hikari) is chapter 132 of the original Naruto manga.
Summary
To make sure that Naruto stays committed to the battle, Gaara begins to slowly suffocate Sakura, explaining that she will only be released if he is defeated. He then attacks Naruto, who protects Gamakichi from harm. Gaara's transformation continues to progress and Naruto realizes that he might have turned out just like Gaara if he hadn't met Iruka and Team 7. Although he wonders if he can really defeat someone driven by so much hate, Naruto attacks, knowing that under no circumstances can he allow himself to lose.
