If you loved Death Note Relight 2: L's Successors, try Death Note Relight 1: Visions of a God
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.

Death Note Relight 2: L's Successors

Death Note Relight 1: Visions of a God
What they share
Both films are directed by Tetsuro Araki, and they both carry the atmospheric, cult, devastating, foreign gem mood tags, and they sit in Animation / Crime / Drama / Fantasy / TV Movie / Thriller territory. If that's the register that drew you to Death Note Relight 2: L's Successors, the second film will land in a comparable space — through a different lens.
What Death Note Relight 1: Visions of a God is
Japanese suburbia. Perpetual dusk. A notebook falling. Light discovers the Death Note and begins his grim experiment, while the detective L closes in. Each player maneuvers, as the body count rises. A dark anime remix of a very familiar tune.
