### Chapter 4: The Guardian in the Shadows
Frothy was walking through the dark streets of the city, feeling a strange tingling in his hands. He knew he was on the verge of another blackout, but this time, something inside him felt stronger, more determined. Suddenly everything went black.
When he regained consciousness, he was in a dark alley. Before him, three bullies were beating a fragile boy, who was crying and begging for help. The boy seemed to have mental difficulties, which made the scene even more disturbing.
Without thinking twice, Frothy charged forward. In the blink of an eye, he was on top of the bullies, a fierce gleam in his eyes. With almost surgical precision, he pulled out a knife he didn't even know he had and attacked. The blows were quick and fatal, and within minutes, the three bullies were on the ground, bleeding and motionless.
Frothy knelt down next to the boy, who was in shock but still conscious. He looked into the boy's eyes and, in a calm, comforting voice, said, "It's okay now. You're safe."
The boy, still shaking, began to cry with relief. Frothy helped him up and led him back to the house. Along the way, he spoke softly, ensuring that the boy had nothing to fear.
When they reached the boy's house, Frothy bent down to eye level and said, "You can't tell anyone about what happened here today. Okay? It's our secret."
The boy looked at Frothy with eyes full of gratitude and said, "I promise. Thank you for saving me."
Frothy gave a slight smile and nodded before disappearing into the night.
### End of Chapter 4
Frothy returned home feeling a strange mix of relief and guilt. He knew he had done something terrible, but at the same time, he felt he had fulfilled a sacred duty. With his imaginary friend by his side, he was ready to face anything that came his way, always keeping in mind his promise to protect the innocent.
