Naruto Jump Remix, 9

The power Sasuke so desperately desires is the ultimate Sharingan, the one Itachi used to massacre his clan: the Kaleidoscope Sharingan. It seems the only way to obtain it is by killing your closest friends, and Sasuke has before him the person who most closely fits that description. The condition for gaining more power is killing your closest friends! Naruto's ninja way clashes with Sasuke's unwavering determination in the Valley of the End!
