Lore & Background
The turning point of her life occurred when she died in childbirth at a remote hospital, leaving behind twin children, Aqua and Ruby. Her death was not just a personal tragedy but a seismic event that set the stage for the twins' quest for truth and revenge, exposing the dark underbelly of the entertainment industry.
In Their Own Story
The rain hammered against the glass of the small apartment, mirroring the storm inside Rina's heart. She stared at her reflection, seeing not the smiling idol B-Komachi fans adored, but a woman running out of time and options. The phone on the table buzzed with another notification she couldn't bring herself to read—another rumor, another lie spinning out of control. With a trembling hand, she reached for the window latch, knowing that tomorrow would be too late. As the city lights blurred through her tears, she whispered a silent promise to the tiny lives growing within her, hoping they might one day see a world where love wasn't a transaction.
Reader's Guide
Rina Tennoji serves as the tragic prologue of the series, representing the dark underbelly of the idol industry. Her role is that of the catalyst; without her death and the subsequent rebirth of her children as Aquamarine and Ruby, the main story would not exist. She possesses no supernatural abilities but holds a natural charisma that made her a top-tier idol before her fall.
Her defining moment is the revelation of her pregnancy by Gorou Amemiya, which leads to her public ruin. Unlike Ai Hoshino, who hides her pain behind a smile, Rina's struggle is raw and exposed, leading to her suicide. Her arc is short but devastating, highlighting how the industry consumes those who cannot fit its impossible standards.
Her legacy lives on through her children, who carry her name and memories while navigating the very world that destroyed her. She remains a ghost in the machine of Showbiz, a reminder of the cost of fame.
