I was shocked when I found out the ages for the Samurai Champloo characters. Mugen is 19, Jin is 20, and Fuu is 15! I always though that Mugen and Jin were in their late 30s and Fuu was in her 20s.
I guess it was just such a socker because of how the 日本动漫 is... a lot of "adult situations" especially for Fuu. But I guess it makes sense because back in these times adult would probably be around her age if not younger.
