MottoI'll solve any problem!

The self-proclaimed boss of Problem Solver 68. Aru expanded Gehenna Academy's Problem Solver 68 club without permission to conduct illegal business activities. She aspires to be seen as a dashing and debonair villain, but her frequent blunders always expose her as a poser.
