The Power of Darkness…!! (闇の力…!!, Yami no Chikara…!!) is chapter 464 of the Naruto manga.
Even though his arm has been ignited by Amaterasu, the Fourth Raikage continues to attack Sasuke. Gaara appears and stops them both from fighting. He asks for a chance to speak with Sasuke, which will also give the Raikage an opportunity to deal with his arm. Gaara discourages Sasuke from a life of hate, citing his own experiences as proof that doing so won't solve anything. Sasuke rejects Gaara's suggestion that he can turn back. Gaara sheds tears for him. When Temari and Kankurō point out that if Sasuke could be convinced Naruto wouldn't have failed and that Sasuke isn't Gaara, Gaara, the Sunagakure bodyguards (Kankurō and Temari) and the Kumogakurebodyguard attack him simultaneously. Sasuke further develops his Susanoo to protect himself from harm.
