Databook isn't reliable when it comes to listing users. Like it listed madara as the sole user of PS...The databook said that only Kaguya has the rinne sharingan eye. I know Madara opened third eye because he absorbed the god tree into his body opening up the god tree's eyes in his forehead.
What does that have to do with accelerating the moon for the tsuki no me project?
I honestly did not read this anywhere in the manga so it's news to me.
