episode 48
She received it from Masquerade on episode 44 but officially use it later on episode 48
yep they do a battel and gaara wins obviously later on, Gaara can officially kill Lee within seconds. In Shippuden Gaara could kill Lee in less than a second. later on in Shippuden, Gaara could kill Lee faster than the speed of light. HAHAHAHAHH that is an exageration. In shipuden gaara is *WEAKER* than in normal naruto because the akatskui take the shikaku
