Raka is a teenager who just entered high school grade 1. He is a quiet and gloomy child. Since he was 7 years old, Raka is often approached by various kinds of nightmares, most of which are dreams about war. He always broke out in cold sweat and trembled non-stop when those cruel dreams came. Until finally he goes into a different dream than usual, where the players in it are not only himself but also several other people including his cousin Arya. There, he found out the real reason for the cold sweat and shaking when he woke up from dreams was not because he was afraid but because he enjoyed seeing blood. Since then he's been trying to figure out what happened to him.
