15 parts Ongoing Karin accidentally gets involved in a murder case at her school. It all started when she accidentally found the body of the school janitor at her school behind the warehouse.
She still clearly remembers the blood pooling, turning the grass red. The body lay sprawled with several stab wounds. The corpse looked like a small animal, helpless before its predator, dead just like that. Before discovering the body, she crossed paths with a man. A tall man with a mask and dark sunglasses covering his face. The man also wore a hat to cover his hair. His clothes appeared to be layered, and he carried a large bag that seemed very heavy.
However, there was something the man could not hide. The clear scent of blood emanating from his body. Karin had a sharp sense of smell and was certain the odor she detected was blood. Chaos erupted in the school environment. People started forming their own opinions. Karin was the one most affected. She was often questioned about the body she found. People kept asking her to recount the story.
At that moment, a new teacher arrived, diverting the attention of the school community. A young teacher with a handsome face that drew everyone's attention. The murder case faded away just like that. The police couldn't find any more clues.
When people started to forget, Karin felt something was off. The young teacher looked strange in her eyes. Karin felt that the teacher was constantly watching her. The teacher also had a blacklist that he showed to his students. He said the book was a record for the naughty children. If their offenses exceeded three times, those naughty ones would be punished.
That's when the next murder began.
