Ai was always a prodigy, having 3600 points on her Enlistment Day. Her time for defeating the Colossal Neighbor simulation was 9 seconds. She was able to defeat a stronger model of Rabbit by herself, which was deemed undefeatable for a lone A-class agent, by Replica. According to Tokieda, she started as a Gunner and later began using Scorpion. He stated that after she joined the unit, they started winning more often, and that she is undoubtedly the team's ace. He also revealed that Ai, like Osamu, used to have a low Trion level. She however claimed that currently her Trion is in the average.
