"Now, for Sure…!!" (今こそ…!!, Ima koso…!!, Viz: Now, of All Times…!!) is chapter 85 of the original Naruto manga.
Guy reveals that Lee is able to open the Eight Gates. Kakashi reprimands him, stating that to teach Lee such a dangerous technique is foolish. Lee opens the first five gates, removing several natural limits on the body that ordinarily keep the user from harming themselves. Lee's speed and strength are drastically increased, allowing him to use the Reverse Lotus. He assaults Gaara, whose sand defences are completely unable to react.
