Spoilers ahead. Bear with me. I'm usually not one for theories like this, but I've found that in the Lupin franchise you need to read between the lines sometimes and almost nothing is canon, so something like this happening could be done light heartedly with the knowledge that it would never affect anything in the series again.
Towards the end, Lupin is shown in a flashback meeting Queen Sakura who is clearly in love/lust with him as she is draped all over him and asks him to take her with him. It's older, with Lupin in his green jacket. Mira, Sakura's daughter, never has a father in the picture or even mentioned in the special. However, Mira and Ran (who, in case you don't know anything about Conan, is a young Japanese girl), are doubles of each other. If we supposed that Lupin was Mira's father, fathering her when he was overseas with Sakura, this might be a tongue in cheek comment that Westerners think all people of certain ethnicities (such as Asian) look alike, as Mira has Japanese blood. None of this ever comes up in the special and although we see a flashback of Lupin with Sakura, he is kind enough not to elaborate on his relationship with her mother to Mira.
What do you think? With all the women Lupin's been with, it's certainly possible he has a few kids running around. I know this was played on a few times (in which the woman terrifies him and the gang by implying he's a father, but clearing it up moments later). |
