Apocalypse? Have You Ever Seen a Zombie with the Kamui Rinnegan?

System. Pure power fantasy. The protagonist is a zombie who awakens the Kamui Mangekyo Sharingan from the start. At the second stage, he transforms directly into the Six-Tomoe Rinnegan while retaining the abilities of the Kamui Sharingan. He also gains all the Rinnegan abilities from Naruto Shippuden, with no side effects. Whenever he kills an enemy, he can strip away their skills with 100% certainty. Along the way, many of the anime he watched as a child will be woven into the story. In the later stages, the protagonist wants to be neither a zombie nor a human. He seeks only to become a higher form of life.
