Iyo

The Fourth Hand. A girl whose Order is seeing the future. She also the one who found Eiji. Anyone who touches her ribbon, that acts like rabbit ears/antennas, will cause her to rapidly become pregnant and soon give birth, which will result in the loss of her powers, although the baby will disappear after a while if not given birth to. She eventually has romantic feelings for Eiji and becomes a love rival with Rin. Her ability is "Star Seeker": the power of Divination. She once combined her ability with Eiji's ability. Originally known as "Subject #23" of the Hoshimiya Agency.
