This is an unnamed ability possessed by Black Zetsu that allows it to record events that it has personally witnessed.
When used in conjunction with its signature Mayfly technique, Black Zetsu can gather data from battles without being detected. In order to show these recordings to others, it must first merge with the recipient. Black Zetsu, over the centuries, claims it was able to record the entire history of shinobi to later show its creator, Kaguya Ōtsutsuki, after her revival.
