Sasha Necron is Misha's older twin sister and the sixteenth-generation heir to the Necron family. Known as the Witch of Destruction, her Magic Eyes of Destruction has the ability to make anything in the universe self-destruct. She is one of the main female heroines of the series along with her sister Misha. Sasha has long blond hair with ribbons and twin tails along with blue eyes as well as a fairly short and petite frame. She is also slightly shorter and leaner than Misha. Sasha's school uniform consists of the standard black uniform for pure-bloods and a Hexagram badge. She also wears two hair ribbons that are colored black with yellow highlights, long black socks that leave her upper thighs exposed and are held by red straps, as well as black high-heel boots. When combined with Misha, she has long white hair and long bangs, and their attire becomes a long white dress. Sasha initially comes off as arrogant and haughty as she takes pride in her lineage as a direct descendant of the Demon Emperor Ivis Necron, and displays great confidence in her power and abilities. She tends to get aggressive to those who she thinks are belittling her efforts and mocking her talent as she was initially hostile to Anos, due to thinking that he was looking down on her. However, despite her temper and impulsiveness, she is shown to be a very competent leader and skilled strategist, as was demonstrated in her team match against Anos, with her subordinates greatly trusting in her and even managing to perform Jio Graze despite initially having doubts in doing so. Initially it appears that she has a negative relationship with her twin sister Misha, as Sasha would often verbally abuse her by calling her a "junk doll" or other insults. However, it is later revealed that the two sisters were close during their childhood and that Sasha has protective feelings towards her, as she got angry when other students insulted Misha. In truth, Sasha didn't hate Misha at all as it is revealed that all of Sasha's previous abusive behavior towards her was a long-term plan by Sasha to get Misha to hate her so that Misha could survive their merger on their fifteenth birthday due to the effects of Dino Jixes, which was mean to forcefully re-fuse Misha into Sasha in order to increase the latter's power. It is shown that Sasha truly loves Misha as her sister as she was willing to accept sacrificing her own life and having Misha hate her in order to save her. Sasha is shown to have a tsundere side to her personality as she has great difficulty being honest about her own feelings, initially in regards to Misha but that became far more apparent in her relationship with Anos. Sasha is shown to have fallen in love with him due to him being the first person who could withstand her Magic Eyes of Destruction, commenting that they were "beautiful". She is very grateful to him for saving Misha's life while also allowing her to live alongside her sister, as she had accepted that he was the true Demon King of Tyranny and showing great pride in being his subordinate.
