峰不二子
In the original anime Goemon's relationship to Lupin starts off more professional than close friendship. By the second anime series, Goemon has developed a true loyalty to Lupin. However, he easily gets annoyed by Lupin's antics, especially Lupin's infatuation with women and Fujiko Mine in particular. He will occasionally oppose Lupin directly when Lupin's jobs or actions do not agree with his morals. He has even promised that the last act he will take with Lupin is delivering his deathblow. Yet Goemon doesn't hesitate to help Lupin in serious situations, and readily assists him any time Lupin works for a just cause. However, in 1978's "The Mystery of Mamo", he claims that he helps Lupin simply so he can keep his vow to kill him himself.
