She began working for Eden in the "Hunt for the Emperor's Arm" and works with a New Code:Breaker, Ikurumi Shiwon. Eden also increased her special power. Thar allows her to release poison in a new form that can even overcome Rei's blue flame and melt his clothes.

However she reveals her true colors and shows that she has changed and attacks Ikurumi and saves Sakura's Mother. She has shown even kindness and compassion and selfishness that even Ogami jumped in the way and took Ikurumi's attacks in order to protect her.
