When Light's father was in deathbed, he looked at Light and confirmed that Light wasn't Kira by his Shinigami eyes since he was able to see his death date.

The only way his death date can become visible is if he doesn't have ownership of a death note with him at the current moment. If Light did not have any deathnote with him at that point, how he was able to keep his memory? And if he had a death note with him, why was his death date visible to his father?

  • If I'm not mistaken, Light kept a Death Note strapped to his body. I don't remember the exact mechanics of this though, so I'd have to check the details.

  • How to Use: XXIII: .......all the memory involving that Death Note will remain as long as he maintains ownership of at least one other Death Note. Mar 16, 2017 at 20:29
  • I believe Light relinquished ownership of his deathnote but still had a small piece of paper from it.

1 Answer 1


it was because Light didn't own the Death Note that was on his body, concealed by his clothing.

When the Kira Task Force got the Death Note from the New Kira in the Yotsuba Group, when Light touched the Death Note his memories returned however Kyosuke Higuchi was still alive and had ownership of the Death Note. with his restored memories Light remembered the details of his plan and used the scrap of the Death Note in his watch to kill him

Light also touches the Death Note while inspecting it, thereby regaining his memories of being the real Kira. Light then uses a Death Note scrap hidden in his watch to kill Higuchi.

Source: Kyosuke Higuchi - Appearance (last paragraph)

as he was holding the Death Note when Higuchi died Light became it's owner. After this Light gave up ownership of the Death Note but kept it on his body so he could retain his memories

Soichiro makes the Shinigami Eye Deal with Ryuk, allowing him to gain the Shinigami Eyes. Using the eyes, he is able to learn Mello's real name, though he is fatally wounded by Jose, one of Mello's gang members, and their bomb. Because Light has given up his Death Note to make his lifespan is visible while keeping one on him to prevent his memories from being erased, Soichiro dies happily believing that Light is not Kira.

So for one to have their memories from their ownership of a Death Note they don't need to be the book's owner, they just need to be physically touching it.
