モーリス

The Register for the Arsene Lupin works. She calls for reinforcements after her world undergoes a full-scale assault by Grimoire's worms. After greeting Eito and Tale, she fights alongside them as they make their way to the prison where Lupin is trapped.

 Like the other Registers, she has complete awareness of what goes on in Paris as well as the mental state of the characters under her watch. She is closest to the image of the ideal Arsene Lupin aspires to, hence Lupin begs Maurice to teach her the skills required to excel as a phantom thief. Ganimard works with Maurice to set up "simulations" allowing Lupin to get actual field experience in stealing precious works.

Although proud of Lupin and Ganimard, Maurice underestimates the strain Lupin is under in constantly having to rely on others to get her out of trouble. She also has trouble getting Ganimard to vent her frustrations safely, when Ganimard goes "off the grid" to binge on whiskey bonbons Maurice has no choice but to ask the Librarians for assistance. /
