Personality
"I’m not as kind as Master Shadow. Don’t think I’ll let you die in peace."

- Nu to her enemies

Nu is a dutiful and hardworking young lady who always interacts with her superiors and customers with a beautiful smile. Beneath that persona, however, lies a dark side and she can be quite ruthless and cruel to her enemies, especially those that slighted her beloved master, Shadow. Her enemies would sometimes be sadistically tortured to make them see the error of their ways.

In her old life, Nu was very passive when she was a young noble girl, following the orders of her family. Despite being controlled throughout her childhood, she was somewhat content with her situation due to the small joys she did gain from it. Even in present day, she held some fondness for her old life.

After meeting Cid, Nu became very loyal to him and has shown to have a crush on him, thanking him for granting her freedom. She displays an open hostility towards anyone who causes the slightest grievance towards him, and would not hesitate to kill in order to protect his true identity.

Powers & Abilities
Although Nu just entered the Shadow Garden organization after being cured, her intelligence, professionalism and physical skills were so strong that Alpha herself validated her, quick rise in rank and making her one of the double-digit Numbers, which she are given a Greek name. She is eventually assigned to be the personal assistant and bodyguard of Gamma, who is one of the Seven Shadows.

Master Combatant
Despite not having the immense strength and mana reserves her superior has, Nu proved to be an excellent fighter as she disarming a man without moving from her stance at least in battle. While Nu doesn't match Gamma's intellect when acting as her assistant, she is the better fighter when it comes to being her bodyguard as she was assigned to handle all of Gamma's fights due to Gamma's extreme clumsiness in coordination and technique of harnessing such power.

Master of Disguise
In addition to her combat skills, Nu is also skilled at disguise. But unlike most members of Shadow Garden, this is her greatest skill as she is an expert in disguising her figure to avoid detection and infiltrate enemy bases. When she meets Cid and accompanying him in the Academy, Nu dressed herself in an academy uniform with an inconspicuous presentation, blending as a background character and she is able to mask her presence during missions. Cid only recognizes her because he remembers her voice.

Swordsmanship
As a Shadow Garden agent, Nu is trained in their advanced and unique swordplay. When she joined her sisters in repelling the terrorists, she used said swordplay to slay numerous attackers.

Interrogation Specialist
Nu is also capable of being an interrogator who uses several methods of torture to crush his victims and force them to reveal their secrets, which shown when she will use any means to get information out of the Cult of Diablos members.

Makeup Slime
By taking the Slimes normally used to create the bodysuits, they can instead be used in specialized masks to disguise someone as another person. Nu applied this to Cid by helping him to be disguised as "Mundane Mann" for entering the Bushin Festival tournament, without fear of being exposed to his true identity as Shadow.
