クレナイノツキ

Kouya, a rookie detective, is walking deep inside the forest. It was two weeks ago, a hand of an unidentified creature washed up on the shore of a river. Hard and thick skin, bristle like an animal, thick fingers and sharp nails, it was not a human's hand. Also, there was a jewel ring on the ring finger.

This mysterious story was featured in a magazine and caught people's attention. Days later, the police found that it was a woman's hand, who had been missing for a month. She went missing when she played golf with her friends nearby. The police confirmed she was attacked by a stray dog, but couldn't explain why the hand looked so differently. They tried to close the case, but her husband wasn't convinced. He didn't want to believe his wife was a monster. He decided to ask a detective to investigate the case, that's why Kouya is now roaming around deep inside the forest.
