Ai Kitora

Height: 161 cm

An all-rounder and member of the Arashiyama Unit—ranked 5th in A-Class—within Border Headquarters.

Like Kirie Konami, she attends the middle school division of Seirin Girls' Academy, an elite private school that has no formal affiliation with Border.

She possesses a proud personality and is demanding of both herself and others. As an elite agent who reached A-rank while still in junior high school, she takes great pride—and harbors a strong sense of elitism—in her status. Because of this, she developed a one-sided rivalry with Osamu Mikumo.
