Delta

The fourth seat of the Seven Shadows. Ages 13 to 15. A dog-type beastman with long black hair. Previously named Sara. Among the Seven Shadows, she stands out for her combat abilities, fighting fiercely with a natural sense for battle. Her sensory organs, such as smell and hearing, are so superior that even Shadow, despite racial differences, admits they are better than his own, making her a born hunter excellent at stalking and detecting prey. She possesses immense physical and magical power, capable of slicing buildings in half, but on the flip side, her intelligence is lacking, and she is weak against trickery. Unlike Gamma, who is too dumb to learn combat techniques, Shadow has deemed it impossible for her to acquire skills, and like Gamma, she fights using a style that relies heavily on infusing her attacks with magic. Normally, she covers her hands with a slime bodysuit to form claws or mimics the weapons of other Seven Shadows, but when serious, she forms a massive sword known as "Iron Mass" and swings it around. Her aliases include "Tyrant," and she is also known as "Cannonball" and "Suicide Bomber."

Even among beastmen, who tend to value combat strength above all, she is particularly extreme. Upon seeing Shadow, she immediately recognizes the difference in their levels and adopts a submissive posture, obeying those stronger than herself, such as Alpha, whom she obeys due to his superior intelligence. However, she does not submit to those weaker than her, and she particularly looks down on and beats up Gamma during mock battles. In Alpha's case, she usually obeys, but during combat, she refuses to take orders, requiring intimidation to force her to listen.

She is extremely poor at "waiting" and will attack prey impulsively if she cannot restrain herself. She can stop if ordered by Shadow, but while waiting, she feels immense stress and ends up destroying various things later.

She does not understand the goals of Shadow Garden or its relationship with the Diabolos Cult at all. She obeys orders from Shadow Garden more out of loyalty to Shadow and Alpha personally, due to the gratitude she feels towards Shadow for healing her body and her belief in meritocracy. She perceives Shadow Garden as a pack with Shadow at its apex.

She seems to have little sense of shame, as seen during a battle in Lindblum when her slime bodysuit, sealed by magic, melted, leaving her in a bikini armor-like state, barely covering herself as she continued to fight. In the TV anime series, after the battle in Lindblum in episode 14 of the first season, and later in episodes 20 and the first episode of the second season, her slime bodysuit remained unrepaired, keeping her in a bikini armor-like state. By episode 6 of the second season, it had finally been restored.

She refers to Shadow as "Boss."
