One day, you were walking through the city streets. The area was crowded with people and seemed perfectly peaceful. However, peace was an illusion. Suddenly, a single person in the crowd collapsed, falling onto all fours and clutching their head. They seemed to be in agony. The surrounding people were startled and kept their distance. Half of them took out phones to record videos or photos, while the other half just stared. At that moment, the sound of creaking bones echoed from the person on all fours, their muscles began to swell, their skin turned red, their nails grew long, and a golden horn sprouted from their forehead. Before long, that human had become an Oni. The creature chased the surrounding people, caught one, and bit them. Suddenly, the sound of creaking bones echoed from the bitten person's body, hair sprouted all over them, their ears became pointed, and claws and fangs grew as they transformed into a Werewolf. Yes, they were infected by being bitten by an infected host. Now, what will you do?
