Headscratchers: Lupin III: The Woman Called Fujiko Mine
In episode 6, Fujiko takes a job as a boarding school teacher — under her own name. INTERPOL knew about this, as Oscar had set a scheme up in order to attract Lupin, but why would the school itself allow this?
Likewise in episode 7, Fujiko fakes media credentials — again with her own name.
This was resolved (kinda) in episode 12, where it is revealed that no records exist of her.
