Nu/Chronology

Tragic Life
Nu was once a noble daughter that dutifully followed the demands of her parents. She once attended Midgar Academy and was engaged to Marco Granger. When she developed the possession, her horrified parents disowned her only for her to be found and revived by Shadow Garden.

Midgar Academy Terrorism
Nu first appeared greeting Cid and his friends. She led Cid to a room where Gamma was. After being informed about the impostors, Cid decided to head out and Gamma had Nu to assist him. The two successfully captured one of the impostors who Cid ordered Nu to personally deal with. Nu proceeded to torture her captive, informing him that she won't be as merciful as her kind master. She then hanged the corpse to deter anymore impostors from attempting the same thing he did.

Shortly after, Nu, who was disguised as a student. She met her master Cid at the Midgar Academy to inform him about the imposters who called themselves Shadow Garden, she informed him as much as she could while collectively asking for disciples since his mind was already broken so he couldn't get much of a report out of him. she incidentally told Cid Kagenō about how the system and hierarchy of the Cult of Diabolos was formed, from the 3, 2 and 1 "children" to the lieutenants and those of the round table.

When the terrorist attack on the Midgar academy occurred, Nu managed to sneak in among the students and then found the corpse of one of the knights who was part of Iris Midgar's group and the injured body of her ex-fiancé who had joined them, between that, Nu discovered that Granger was still alive but unconscious, then she met with Shadow and he informed Nu about him draining and sealing of magical power in the Academy, much to Nu's surprise (believing that she that Cid had solved it, not knowing that it wasn't him, but Sherry). Nu congratulated him and told him to get materials to help him investigate the problem for later, shadow would fix it.

When Cid left, Nu threatened his ex-fiancé in a loud voice, believing that he had heard the entire conversation that Nu had with his Master Cid, but later found that he was totally unconscious and injured. Nu coldly told him that he is lucky, because if he were to learn the identity of her master, she would not hesitate to kill him.

God Of War Tournament
When there was the tournament of the goddess of war. Cid went to visit the company to help him dress up to participate in the tournament, Nu helped Cid disguise himself under the identity of Jimena with a slime makeup that Nu uses.

Great Trade Alliance Conflict
During the Trade Dispute Incident, Nu comes to inform Gamma and Alpha, who were puzzled and saddened by their lord's alleged betrayal, that Gintou, the leader of the Trade Alliance, had relations with the Diabolos Cult. causing Alpha to begin to doubt and silver that if Gintou was a collaborator of the Cult, Shadow already knew it and what he wanted to destroy was something else. Then Beta appointing Eta's help, informs Alpha, Gamma and Nu, that Cid did not betray them, that he was helping them to overcome the financial crisis of counterfeit bills, which generated joy and relief for all besides that Delta was not dead.
