Sasha initially appears arrogant and prideful, confident in her lineage as a direct descendant of the Demon Emperor Ivis Necron and in her formidable power. She can be hot-tempered and defensive, especially toward anyone she believes is mocking her abilities, as seen in her early hostility toward Anos. Despite her impulsiveness, Sasha proves herself to be an exceptional leader and strategist, earning the full trust of her subordinates during her team battle against Anos, where they successfully executed complex magic under her command. Beneath her pride, Sasha possesses a deep sense of responsibility and devotion to those she cares for.

Her relationship with her twin sister Misha reveals her hidden warmth and selflessness. Although Sasha initially treated Misha coldly and insulted her as a “junk doll,” this was only a façade to protect her. It’s later revealed that Sasha’s cruel behavior was a deliberate act to make Misha resent her, ensuring Misha’s survival during their forced fusion on their fifteenth birthday. In truth, Sasha deeply loves her sister and is willing to sacrifice herself for her happiness. Over time, Sasha’s tsundere nature becomes more evident, especially in her growing affection for Anos. She falls for him after he acknowledges the beauty of her destructive eyes and saves both her and Misha, leading her to fully accept him as the true Demon King and to take pride in serving by his side.

Fifteen years before the events of the series, Ivis Necron used the forbidden magic Dino Jixes in an attempt to create a perfect vessel for the Demon King’s reincarnation. As a result, newborn Sasha was split into two beings, one half retaining her original identity as Sasha Necron and the other becoming Misha Necron, her “younger twin sister.” Because Dino Jixes was a spell of separation and fusion, it dictated that on their fifteenth birthday, Misha would merge back into Sasha, ceasing to exist as an individual.

During their childhood, Sasha’s uncontrollable Magic Eyes of Destruction made her dangerous to others, as anything she looked at risked being destroyed. Misha was the only one able to stay by her side and meet her gaze without harm. With Misha’s support, Sasha learned to control her destructive power and stop hurting those around her. However, Sasha couldn’t accept the cruel fate that awaited her sister. Determined to save Misha, she devoted herself to researching magic that could defy Dino Jixes. She eventually developed the spell Zexis, which synchronized their sources so that the spell could no longer distinguish the original from the duplicate. To complete her plan, Sasha intended to use Delt to make Misha the original person instead, but for the spell to succeed, Misha needed to reject her. Knowing this, Sasha chose to act cold and hostile toward her beloved sister, enduring Misha’s hatred so that Misha could live, even if it meant sacrificing herself.

Sasha possesses tremendous magical power, earning recognition as a prodigy even among the Chaos Generation. From the beginning of the series, she was already considered a highly talented demon with exceptional potential. After obtaining a complete source, her dormant abilities were fully awakened, significantly amplifying her strength and control over magic. Her power increased even further after undergoing a week of training under Anos Voldigoad, who confidently stated that she would not lose to any modern demon.

In addition to her raw magical strength, Sasha has shown remarkable intellect and creativity in the field of spell theory. She possesses a deep understanding of spell structure and magical composition, capable of constructing complex spells from scratch. Notably, she created two powerful spells, Zexis and Delt, both of which required immense knowledge and precision. It was said that developing new spells typically takes years of research, further emphasizing Sasha’s genius and dedication to her craft.

Known across the demon realm as the Witch of Destruction, Sasha is a master of Destruction Magic. Her rare Magic Eyes of Destruction grant her the ability to annihilate matter and magic alike, making her one of the most dangerous magic users of her generation. She demonstrated mastery over Vebzud, a spell of immense destructive power that only Anos himself had been capable of wielding during the Mythical Age. These abilities make Sasha not only a prodigy by name but a true powerhouse among demons.
