The rundown
The Fourth-Dimensional Devil (2026)
On the night of a concert, former students gather around the renowned conductor Professor Ke. Dayung, who has long since abandoned music, is among them. During the reunion, Professor Ke suddenly cries out “Devil” and collapses. As confusion spreads through the hall, only Dayung notices something strange: Professor Ke’s coffee cup begins to move silently on its own.
It shares its release window with Resident Evil, so expect the two fanbases to be reacting side by side.
The theatrical release lands September 18, 2026.
