"Sasuke's Decision: Pushed to the Edge!" (限界を越えて… サスケの決断!!, Genkai o Koete… Sasuke no Ketsudan!!) is episode 75 of the original Naruto anime.
Gaara, who has partially transformed into Shukaku, has dramatically increased his strength and speed, as well as the level of difficulty Sasuke faces fighting him. Sasuke uses his Chidori to slice the Shukaku arm off; however, the sand reassembles his arm. Wounded once more and in pain, Gaara only becomes more determined to kill Sasuke. Unable to use the Chidori on his own anymore, as he can only use it twice per day, Sasuke resorts to using Fire Release: Phoenix Sage Fire Technique along with a Fire Release: Great Fireball Technique, but the attacks do no damage to Gaara. Realizing that his Chidori is the only technique in his arsenal capable of taking down Gaara, Sasuke is forced to use his cursed seal, which grants him additional chakra, so that he can attack Gaara with another Chidori. However, the Chidori again only manages to destroy the Shukaku arm, which Gaara is able to regenerate using the sand. Sasuke collapses due to the use of the cursed seal, unable to move. As Gaara rushes forward, prepared to kill Sasuke, Naruto arrives, kicking Gaara in the face. Sakura and Pakkun also arrive.
