The Day of Parting…!! (volume)

Synopsis
Naruto and Sasuke prove equally matched. In attempts to gain victory, each calls upon their unique strengths: Naruto and the demon fox's power, Sasuke and his cursed seal's reserves. Naruto and Sasuke fuel their sources of strength into their Rasengan and Chidori, respectively, and attack one another. Once the energy created by the clash dissipates, Sasuke stands over a defeated Naruto, though his injuries leave him little better off. Although he contemplates killing Naruto he eventually decides against it, realizing that that is what Itachi would want. Deciding to get power in his own way, Sasuke goes to Orochimaru, ready for whatever is necessary to get stronger. Kakashi arrives to retrieve Naruto and take him back to Konoha, where he, like the rest of the retrieval team, are healed.
