Thriller Game: I Pulled the Slit-Mouthed Woman's Teeth and Made Every Ghost Cry

[Horror game + System + mystery + no female lead, with a little horror.] The horror game begins, and I enter the Haunted Inn instance. The landlady is the Slit-Mouthed Woman, who eats heads like walnuts. The ghost manager is a perverted female ghost who eats children alive. The ghost waiter is a lecherous ghost, and the ghost chef likes human flesh. “Vengeful ghosts, back off! Take one more step, and I’ll kill every last one of you!”
