Anna is a student who operates as part of a team defending Earth from extraterrestrial threats. She attends an academy where she investigates unexplained phenomena including alien abductions and infiltrations by hostile Reptilians. Alongside friends Ray, Tyler, Halle, and Eisuke, she uncovers the truth behind these events. With the mentorship of a professor, she employs specialized devices to contact benevolent aliens, leading to interplanetary voyages aboard UFOs. These journeys reveal cosmic truths and past life connections. She also engages in time-recovery operations to rescue comrades stranded in ancient epochs and confronts institutional resistance to expose cosmic conspiracies. Anna has waist-length blue hair, green eyes, and a youthful demeanor, consistently wearing a school uniform with hair clips and a ponytail. Her efforts remain focused on collective defense, leveraging scientific rigor, tactical coordination, and cosmic exploration to counter adversarial forces.
