Hikaru Kuro, Tyson Oyami, and Mizara Hyo. Sasuke Uchiha was her former best friend, but her other friends soon replaced him.
There are two ways to achieve the Mangekyō Sharingan. The official way is to kill you best friend or someone really close to you. It is not actually the killing that grants it, but the feeling of loss. It is unknown how Hatake Kakashi was bestowed with it but the common explanation is that he got it from the emotions of losing his best friend Uchiha Obito. The Second way is through vigorus, extensive training of the body and mind. This has been seen in one of the founders of Konohagakure, Uchiha Madara and his younger brother Uchiha Izuna.
