She was trapped inside the Blue Rainbow Crystal and then reborn inside Motoki's girlfriend, Reika Nishimura. In episode 29 Zoisite extracts the crystal and transforms Reika into Rikoukeidar.

Sailor Moon healed Reika with Moon Healing Escalation, thus destroying the youma within that was Rikoukeidar.
