After beating the maze and granting Zen's wish to have his immortal life ended at the hands of a hero, Satou became No.7's new master and is renamed as Nana.

Trivia

 * Nana always uses "Masuta" to call Satou while all other members uses "Goshujin-sama". They both mean "Master" in English.
 * She gets jealous and possessive about Satou if someone else uses "Masuta" to address Satou.
 * Nana has 6 "sisters" in the WN, but 7 in the LN. Like Nana before being named by Satou, each sister is simply referred to by number. In the WN version, they are killed when Zen uses "Limit break". In the LN, Satou saves all of them and they go on a separate journey.
 * Has a strange manner of speaking as if she's reading off a play script, such as making a statement, followed by "So I declare", similar to the clone sisters in the "A Certain Magical Index" series.
 * In her POV side stories, Nana's thought process is like that of a primitive computer AI executing commands, not unlike how she speaks out loud...a very different personality from her sisters, some of whom speak perfectly normal as anybody else.
 * While in a drunken state, Nana mentioned that it was possible for a homunculus to mate with a human, which in an interesting anecdote because it's repeatedly stated in this series that it isn't possible to interbreed between different races in this world, (like human x demihumans, or human x elves) with the exception of humans x longearkin.
 * Loves all things cute, especially children, which she calls "young organisms" ("larval creatures" in the official English light novel and manga).
 * She is willing to disobey Satou when it comes to matter young children, almost abducting them on several occasions and even buying 2 young slaves against Satou's wishes.
