'Nana' is one of the possible pronunciations in the Japanese language for the number 7, and it ends up being used as a feminine name with a possible double meaning in anime and manga.
One of the Japanese
Numerological Motifs.
Four Is Death is another one.
One Two Three Four Go is a
Sister Trope.
Examples:
Anime and Manga
- Elfen Lied features experimental subject Number Seven, or "Nana" as her father figure calls her.
- Loveless has a Hikikomori called Nana who only briefly shows up in the anime but plays a larger part in the manga, and her name likely refers to her dependence on computers. She's referred to as "Seven" in the Tokyopop manga release.
- Both stars are named Nana in the manga Nana, and live in apartment 707 — effectively using this trope as its entire premise. One of them is called "Hachi" (short for Hachiko, but also meaning eight) to differentiate between them.
- In Shichinin no Nana (Seven Of Seven), a girl named Nana is split into seven personality fragments.
- And all those fragments get names that describe them and start with Nana. The exception is the eighth, bad Nana, Jamanana.
- Best of all, the primary Nana's Japanese voice actor is also named Nana.
- In Puni Puni Poemi, the seven Aasu sisters are all named after numbers, in reverse age order. So the youngest sister is named Hitomi (from "hito" - one), and the oldest is named Nanase.
- Kodomo No Omocha's Sana is named after her birthday, March 7.
- Tsuna is occasionally associated with the number 27. It's on his door, as well as the mitten form of his X gloves. Tsu sounds like two, and na is seven. Thus, 27.
- Saki of Futari Wa Pretty Cure Splash Star is associated with flowers (hana); naturally, her birthday is August seventh (ha - eight, na - seven).
Video Games
- Mega Man X: Command Mission has a reploid named Nana as your Mission Control, with the number seven displayed prominently on both her breasts.
- Nanako in Tsukihime/Kagetsu Tohya. Originally... well, not quite originally since she was a human once with a presumably human name. Er. Anyway, previously, her name was Seven, in English, as she's the spirit of the Seventh Scripture; a fusion weapon created from her soul and the horn of a unicorn monster. Arihiko translates that to Japanese, Nana, and then adds a feminine ending to it. There, Nanako the horsegirl, spirit of a BF Harpoon Gun that shoots pages of the Bible. Yep.
- Higurashi No Naku Koro Ni gives us Reina, the original name of Rena, which is a combination of 0 and 7 and refers to the creators' name, 07th Expansion.
Real Life
- "Na na na" in a song is sometimes shown as the English number 7 in karaoke. One example of this is Konjiki no Gash Bell's sixth ending
.
- Nana Mizuki WHORES out this trope for her singing career up to a point that she charges $77 dollars for her concert tickets.
