So it says a thousand years have past. Yuki brings flowers and Bloody Rose to the Kiryuu grave and basically says her goodbye to Zero. As soon as she leaves Zero’s grave she goes and kills herself.
Yuki admits to wanting to die like Zero did. SOON. We all know how terrible Yuki is at dealing with her thirst. So I doubt she would stick around for a couple hundred years UNLESS Ren was a child and needed to stay till he was grown.
Tragic BUT an option.
Whats the difference between 900 and 1000 years for Zeki???? Nothing really for them. Im pretty damn sure 1000 years past before Zero died. When it says 1000 years, it could mean 1000, 1100,1200,1500, ANY OF THOSE. Hino is vague as fuck as we all know, (unless she ya know, WANTS TO KILL PEOPLE)
