Alice is a descendant of Victorique and Kujo.
The similarities:- Both Victorique and Alice are shut ins with little in the way of social skills.
- However, this does nothing to prevent them from solving mysteries.
- Both keep assistants to gather evidence for them.
- Both have a "thing" for their assistants.
- In Alice's case, it's much less clear just what her feelings for Narumi are, but she seems to have a crush on him.
- Both are picky eaters.
Unlike many "X is a descendant of Y" theories, these three have the benefit of being connected by country. Alice seems to have gotten Victorique's personality and Kujo's looks.
