Medical Expert, Trapper, Exper Espionage Agent, Skilled Combatant
Mira is almost always covered in bandages looking somewhat like a mummy. She has dark skin, a tattoo on her upper shoulder, blue eyes, and wears her hair in dreadlocks which may be a reference to both Egyptian mummies found with dreadlocks as well as the rastafari movement early on referred to as the "Young Black Faith".
When on a mission, Nygus still stays true to her mummy theme with a few changes: She wears green military pants and a white top. In her earlier appearances, the top is omitted and instead has several bandages covering her upper body. She is later seen with a military style jacket.
Mira's personality appears to be matter-of-fact, not allowing personal feelings to cloud her judgment and not being afraid to tell people the truth. She was certainly not afraid to remind Black Star that he is only human, despite his obvious hatred towards comments that compare him to anything but a God and remarked that he is walking the path of a Kishin. She also questioned Marie's actions on going with Stein, stating that she won't find happiness with Stein and that he is always alone.
Mira also seems to be somewhat cold. When Black Star was kicked in the testicles by Patti, he stated, while in pain, that it was unfair. Mira ignored his plea, stating that it was his fault that he turned his back to his opponent even after the match had begun.
Despite this, Mira has shown kindness. Mira, along with Sid and Spirit, let Stein go free instead of arresting him. When Mifune and Black Star were fighting for the final time, Mira wanted to intervene for Black Star's sake when Sid argued he had to deal with the fight on his own. She also previously showed concern for the boy using the demon blade mode when it was believed it would kill him.
- Mira is partnered with Sid and plays the role of Sid's weapon. Seeing as how Sid was classified as a knife meister before Nygus' introduction, it can be thought that the two may have known each well before they were actually seen together. When seen together, though, they show tactic respect towards each other as well as work well together.
Demon Weapon Form: Combat Knife: Mira's weapon form is a combat knife, including a sheath, as can be seen in the anime where the Kishin eggs are drawn into the sheath.

Medical Expert: She is seen working as a Nurse at DWMA. Shes also seen aiding injured comrades in battle.
Skilled Combatant: It can also be concluded that Nygus is an athletic person. She supervised the sprints of the students and was seen supervising the sparring matches between Patti and the other students of the academy. Also, Seeing as she supervises sparring matches, she's most likely skilled at unarmed combat. How much is unknown.
Expert Espionage Agent: She often accompanies Sid on missions that involve stealth and infiltration.
- It seems that Sid and his weapon, Mira Nygus, use an "Undead" theme in the series, with Sid being a zombie and Mira covered in bandages as a mummy. Their attacks match the theme too, as does his ability to use his tombstone as a weapon.
- Mira's last name is a pun on how the word 'knives' is pronounced.
- Mira appears to take the form of Sid's gravestone when she resonates with him.
