Nagi Jinno  

Angel Zero, 神野 ナギ

Jibril, the newest member of the Devil Angels team, is actually a computer program named N.A.G.I., or New Angelic Gaia Interface. She's activated when the situation becomes too dangerous for a human to handle alone. After the threat has been neutralized, she assists with the main mission, which involves Rika and Hikari being captured by an unknown force.
