Japanese Characters double forename I have seen quite a bit of anime and manga now, and I believe I haven't seen a single japanese character with a double forename.

Question: Is there any anime with characters having a "middle" name? Also possibly interesting is, where these Characters originate? Are they "foreign" or are there japanese characters with a middle name?

To clarify i don't mean a Title or Nickname like Aisaka "Tenori taiga" Taiga (逢坂大河) from Toradora.
Middle names are not in Japanese culture. Japanese people at birth are given a first and last name (or a surname and forename). In the rare occasions that you see someone with a middle name, it is usually one of the following two things. They are either of mixed descent, or a woman marrying a man, and using both her original surname as well as the spouse's surname.

With that said, double forenames don't exist in Japan and most other Pacific Asian countries.
And because Japan doesn't use double forenames, Japanese anime are also inclined not to use double forenames.

There are some series that have used double surnames though, but they were never full Japanese characters. The characters would be of foreign ethnicity and names would be English names written in kata kana.
