Ghosts from the Past (幽霊自其の過ぎ, Yūrei ji sono Sugi) is the sixth episode in Riyan's part of Naruto Raijuu: The Beginning.
The man called Ibitsu kills the remaining ANBU, much to the astonishment of Tatsu. He then goes on to restate his name, and then tells them that he is the father of Madara Uchiha. For a few minutes he gives Riyan a bio of the Uchiha clan's past. He tells of the discovering of the Mangekyo Sharingan, and how he himself got an Eternal Mangekyo Sharingan. Riyan asks what he is to do with this information, to which Ibitsu responds, "everything".
Ibitsu elaborates that the village's choosing of Mataiden as sacrifice to end the Third Great Shinobi War was no mistake. The village had somehow found out that Mataiden's immature Sharingan possessed a technique which could wipe memories with eye contact. Fearing that power, the village used Kumogakure's demands as an excuse to kill Mataiden. This episode ends, showing Riyan's immense shock.
