Connie Rokusaki bursts onto the scene as a Nanastar Studio co-manager, immediately proclaiming herself the "Talent Gamaner" and guiding the player in recruiting and training idols. She radiates constant, bubbly energy, often stirring up trouble yet proving a deeply compassionate counselor for trainees. Her distinctive look features pink hair with electric blue undertones, glasses, and a signature pink suit. Numerous characters observe her uncanny likeness to Nicole Nanasaki, the vanished leader of the disbanded Seventh Sisters unit, noting their reversed hair colors and shared vibrant spirit—hinting at an undisclosed link.

Her secret soon unravels: Connie is Nicole Nanasaki, who adopted the alias "Connie Rokusaki" after the Seventh Sisters dissolved in 2032. This disguise let her mentor Nanastar's new generation while concealing her true past. Rona Tsunomori, a devoted Seventh Sisters fan, recognizes Connie as Nicole early on but guards the secret.

During EPISODE 4.0 (summer 2035), Connie's resolve falters. Spurred by Rona's encouragement reigniting her confidence, she discards the Connie persona and reclaims her identity as Nicole. She subsequently departs Nanastar without explanation, an absence noted by the manager and suggested to have distracted Haru. Her exit leaves deep emotional wounds, particularly on Momoka Serizawa and Shinju Harumi.

By EPISODE 5.0 (2043), Connie remains absent from Nanastar, missing even the disbandment of 777☆SISTERS. Her eventual return confirms the Connie identity is permanently gone. Rui Wakaoji observes she is "no longer Connie Rokusaki or the Nicole Nanasaki I used to know," signifying her full transition into an ordinary woman. This marks the symbolic end of the Connie Rokusaki persona, effectively concluded in 2035.

Her nickname "Germane" (a scramble of "Manager") nods to her role, but her true legacy is sparking Nanastar's revival while wrestling with a hidden history.
