Laetitia (full name: Laetitia Bresson ) is the female lead and deuteragonist of Lupin the Third: The First , the first fully 3D CGI theatrical film in the Lupin III franchise. She is an original character created for this film and does not appear in the original manga or previous anime series.
Unlike many femme fatales in the Lupin universe (e.g., Fujiko Mine), Laetitia is positioned as a sympathetic, bookish, and morally driven character who serves as both Lupin’s emotional anchor and the key to the film’s central mystery. | Attribute | Details | |-----------|---------| | Japanese VA | Suzu Hirose | | English VA | Lexi Marman Cowden (English dub) | | Age | Late teens / early 20s (implied) | | Nationality | French | | Occupation | Archaeology student / museum researcher | | Affiliation | Bresson family (granddaughter of Professor Bresson) | | Specialty | Linguistic analysis, historical research, code-breaking | Backstory & Role in the Film Laetitia is the granddaughter of Professor Arsène Bresson , a renowned archaeologist who discovered a hidden diary belonging to the real-life Nicholas Flamel (a 14th-century scribe and alleged alchemist). Before his death, Bresson hid the diary inside a special security box that can only be opened using a unique melody.
Laetitia is not a typical Lupin character—and that’s exactly why she works. She represents what Lupin could be if he chose legacy over loot, and she remains one of the most memorable original characters in the franchise’s long history.
Laetitia works at a museum in France, living a quiet life dedicated to her grandfather’s research. She inherits his notes and a mysterious bullet-shaped locket (which later proves to be a key). When Lupin III breaks into the museum to steal the diary’s container, he finds Laetitia already there, trying to protect her grandfather’s legacy.
