Iris comes across as a careful and bright person who can't leave a troubled child be without help.
Long before the Florian family arrived on Eltria, Iris saw her homeworld destroyed by Yuri. For unknown reasons, she lost her physical form - taking refuge inside a computer device within a church still intact on Eltria. Waiting several years for a chance to have her revenge, she came to befriend Kyrie Florian and planned to find Yuri with her help. Though it pained her to do so, she decides to manipulate Kyrie's wish to save her dying father in order to be brought to Earth.
Once in Uminari City, Iris and Kyrie stole the Tome of the Night Sky from Yagami Hayate and took on Takamachi Nanoha and Fate T. Harlaown in combat in order to record their data into Iris databank. Afterwards, Iris summoned the Materials; Dearche, Stern and Levi from the tome and gave them bodies from the data she had stored. Iris soon found what she was looking for, the Eternal Crystal holding Yuri.
After uploading a virus to Yuri's system to gain control of her, she used Yuri's powers to give herself a body. Telling the truth about having deceived Kyrie to her face, Iris gives her the choice of fleeing before she enacts her revenge, as an act of good will for helping her. Kyrie refuses, but freezes when she tries to shoot Iris. Kyrie's sister, Amitie fires at Iris in Kyrie's stead, though the shot merely graces her cheek. Iris unleashes Yuri's powers upon the mages in the nearby vicinity, with only Kyrie, Amitie and Nanoha there to resist. 
The outcome of the battle above Uminari will be detailed in the upcoming 2018 movie Magical Girl Lyrical Nanoha Detonation.
