Runaway Exorcist (Yuu Kanda Love Story)
Sara was one of the best exorcists at the Black Order ever since she joined at age fourteen, infamous for quick and neat exterminations of Akuma. When she turned nineteen, though, things started to go downhill. She started taking longer on missions, and the towns she would destroy the Akuma in would be in ruin after the job was done. Even Kanda, one of her closest friends, doesn't know what's up. Will anyone find out what's wrong before it's too late?
