It has been thousands of years since this monster appeared, Japanese society has always been haunted by a soul-sucking creature, or Japanese people usually call them Tamashī o suu ikimono. This monster often kidnaps people, especially children and women, then sucks their souls and uses them as food while their bodies are left to rot.

Their emergence created unofficial organizations. The organization contains troops who are trained to eradicate the monster, they are required to master sword techniques and later each hunter will be given a stone to lock up the creature.

But there is a legendary story, that there was a doll made by a royal princess to defeat and suck the creature. This doll is very powerful, it can easily defeat the monster with the sword and magic contained in their body. The doll was made by the princess hundreds of hundreds of years ago, and its existence is still in doubt. People are always trying to find this doll.

Tonight, a hunter, Hayate, is assigned to eradicate monsters on Mount Takao. After finishing killing several of the monsters, Hayate walked through the forest. His gaze didn't stop seeing a girl who was sitting next to a large rock, she just sat and closed her eyes.

Hayate immediately ran towards her to check on the girl, he suspected that the girl was a victim of kidnapping from a monster. "Hey!! are you okay?" he looked at the girl, her face looked pale.

Out of concern, and to check whether the girl was still alive or not, Hayate reached out his hand to touch the girl's wrist. But he was surprised when he held the girl's hand, her hand was hard as if it were not made of flesh.

"Wait... why is this? Her hands are hard?" he was really confused, then suddenly the girl opened her eyes, her gaze was empty and cold, staring intently at Hayate. Suddenly he immediately let go of her hand and walked away.
