I don't think Kimimaro exists really in the end.

When he turned the Rotary press in reverse, it didn't buy back the future, exactly... It printed new futures, essentially.

That's why there was a different family at Hanabi's house.

Just like you can always print new money, but you can't replace a bill that's been lost. That serial number is gone forever.

Kimimaro doesn't exist in the future he created/bought for everyone. It's likely he's dead or essentially disconnected from the timeline... A walking ghost.

Basically, anything that had anything to do with the Far East FD and Midas Money was replaced with a new future. That includes the yen, and all parts of the entre's lives that had to deal with the FD.
That's why Takedazaki ends up disappearing (he was too connected to the FD), and Sato seems to have a new life... (she wasn't as deeply connected).

Kimimaro can't be an Entre again, even if he wanted to. He doesn't have any future OR present anymore. All he has is his memories of the past (that picture).
