The second member of the Numbers was designed while having in mind the need to produce a unit capable of performing long-term infiltration missions in an independent fashion. Her 'IS' allows her to reshape her body's appearance and is especially calibrated to deceive the usual inspections made over one's self in most of the TSAB-administrated worlds. While in missions, her status quo is a classified information even among the other Numbers and the only ones who knows about it are Jail and Uno. Scaglietti's influence over Due is the strongest among the Numbers. She was Quattro's mentor, who inherited many traits of Due's psyche and personal ambitions as a result of the time that they spent together. After the completion of her long-term missions in stealing the Shroud of the Saint King and assassinating the TSAB High Council, she looked forward to be reunited with Scaglietti and her sisters, especially those designated with numbers 6 to 12, who she had never met before. In episode 24, she is killed by Zest after killing Regius. In the SSX Sound Stage, she is referred to by Jail, who asks the TSAB to give her a decent burial in return for his services towards the Bureau in the sound stage. (Source: Wikipedia)

Along with Otto and Deed, Sette was one of the last Numbers to be completed. Nevertheless, she possess outstanding fighting capacities, proven by the fact that she helped Tre take down an army of TSAB Air Forces' mages during her first real-life combat experience. She was tutored by Tre, who gave her a strict and severe training. Because of that, Sette has great respect for the older woman and even share some of her personality traits. Sette was defeated and captured by Fate. In the StrikerS epilogue, it was shown that she was the only late generation Number kept at the high-security facility along with Scaglietti, although this has probably due to her loyalty to Tre than to the Doctor. She is also the only Number in the SSX sound stage who is not given a speaking role or mentioned in any way. (Source: Wikipedia)

She also received mental implants to optimize her intel management and general mental reflexes.

She is the first Number ever to be created and Scaglietti's personal secretary. With a calm and collected personality, acting for Scaglietti's benefit is always her utmost priority. Uno is greatly respected by her sisters due to her seniority and none of them will disobey a direct order from her.
