Yuurei Shoujo

This spectral entity resides in Keroro's former storage room, a space she haunts due to a tragic past involving a hidden Keronian. Imprisoned for concealing a creature resembling Keroro, she died at ninety, a fate she escaped through the help of the Keronian. She frequently watches Keroro and his companions, a silent reminder of her life and the one who ultimately freed her. Her true identity is only revealed to Momoka during her transformation into a ghost seeking proximity to Fuyuki.
