Nemu

From Kokorodatabase

Nemu (眠る, sleep), supposedly, is the eldest child of Yuna and Tidus, making her Kanna and Rakka's elder sibling. However, she's never mentioned except in passing, and has been stated to have left home years ago in search of starting her own story. Nemu is not to be confused with the Nemu that once appeared as a Digidestined in Mirror

[edit] So why does this page exist?

It doesn't. D: Nothing exists. The Matrix is everywhere

Or, to be more truthful, it exists because apparently, Nemu, sooner or later, will make an appearance. But you didn't hear that from me
