[Water Monster] Name: Water Monster Place of Appearance: Arakawa Natural Park Background Story: Five years ago, a horrific home invasion and murder occurred in Hachimachi, Arakawa District. Only one person in a family of four survived. The police spent a long time but the murderer has not been found, and finally the case was sealed. But since then, rumors of being haunted have spread in that place. People's pets suddenly went crazy, and stray cats and dogs began to attack humans wantonly. After investigation and treatment failed, a large number of pets were abandoned or disposed of and buried in the Arakawa Nature Park. However, the rumors of hauntings have become more and more intense, and many people even said they saw water ghosts. Although nothing harmful happened, many people moved away from here. The water monster was born after being infected by mysterious energy after the murder and absorbing the resentment of stray animals. However, before it could fully grow, it just turned into a physical entity when it encountered a mysterious man in black and was destroyed by him.

From weak to strong, they are cat, dog, tiger and fierce (set by the protagonist himself). The official setting is A B C D. Water Monster Strength Recognition: Cat Level/D Level
