Prologue: demons prey on humans, drain glowing souls, and feed them to Gwi-Ma. Stylised, not gory -- still people going out like lights. Sets the rule of the world before the first song.
Theme. Soul-eating is death with a fantasy costume. Children who already worry about 'something taking me' can file this as a night image even when the art is graphic and cool.
What to say. You might say: 'This is the film's demon rule -- they take souls. If that image is too much, we start when Huntrix are on the plane.'
