Death Note: New Generation S01E02 - Ryūzaki's Chapter: Dying Wish

Ryuuzaki, the new successor to "L" is helping with cases around the world, sometimes helped by "J" and in contact with Near who also acknowledges him as L's right successor. He finds himself working on a closed-room murder case that is caused done by Death Note. He finds the perpetrator rather different from old Kira, and on top of that, he finds new Kira is also looking for that Death Note owner, thus realising there are at least two Death Notes out there and he's set to collect them all. But this time alone, so tragedy like with Watari doesn't happen again.
