I'm not sure specifically as it could refer to many things. It might be about a horror story within the context of the animation industry, perhaps a story that causes a 'fever' or intense interest among animation fans due to its particularly terrifying or engaging plot.
The atmosphere is key. Dark colors, spooky music, and eerie settings like old mansions or abandoned hospitals can immediately create a sense of dread. For example, in 'Another', the fog - covered schoolyard adds to the overall creepiness.
The atmosphere. If it can create a sense of dread and unease from the start, like in 'Another' where the gloomy school setting and the rumors of death set the mood right away. Also, the design of the monsters or scary elements. In 'Corpse Party: Tortured Souls', the distorted and ghostly figures are truly terrifying.
The atmosphere. If an animation can create a really dark, gloomy and tense atmosphere, it's already halfway to being scary. For example, using dim lighting, eerie sound effects like creaking doors or howling winds.
There might be some sort of malevolent force as a character. It could be a ghost, a demon, or some other supernatural entity. In many horror animations, these types of characters are used to create the horror element. For example, a shadowy figure that lurks in the background and causes all sorts of trouble for the other characters.
The disturbing visuals might be one reason. In horror animations, often the way the characters are designed, with distorted features and strange postures, can send chills down your spine.
The 'Corpse Party' series is also a popular horror animation. It involves a group of students who are trapped in a haunted school filled with vengeful spirits. The story is full of gore, jump scares, and a really dark and foreboding mood that makes it quite terrifying.
There's 'Corpse Party'. It takes place in an elementary school that was built on an old site with a tragic past. A group of students perform a charm that goes wrong and they are transported to a haunted version of the school. There are terrifying apparitions and the students have to face their worst nightmares. It's full of gore and horror elements that keep you on the edge of your seat.
One common element is the blurring of the line between the animated world and the real world. For example, characters from the animations might start to interact with the real - world characters in a menacing way.
