Made in Abyss: Dawn of the Deep Soul

Made in Abyss: Wandering Twilight
What they share
Both films are directed by Masayuki Kojima, and they both carry the body horror, dread, foreign gem mood tags, and they sit in Adventure / Animation / Fantasy / Mystery territory. If that's the register that drew you to Made in Abyss: Dawn of the Deep Soul, the second film will land in a comparable space — through a different lens.
What Made in Abyss: Wandering Twilight is
Silence presses down on a cavern lit only by glow-worms. Riko and Reg descend into the third layer, a forest of towering fungi swaying under an artificial sky. Riko tastes air thick with spores. Time dilates when Riko’s Curse first flickers beneath her skin. The deeper they go, the harder the whispers cling. A David Lynch-meets-Miyazaki labyrinth where wonder curdles into dread.
