Pietro is a supporting character in the anime Romeo × Juliet. He is one of the mine workers who come into contact with Romeo during the prince's time among the laborers. Like his fellow miners, Pietro is initially distrustful and unreceptive toward Romeo, and he does not accept the newcomer or his conduct at first. Despite this wariness, he shows a notable degree of courage, as he is bold enough to play a prank on Romeo in the dining hall, an act that distinguishes him from the other workers who mainly keep their distance. His role in the story is that of an ordinary laborer whose path crosses Romeo's within the mining community. Over time, his attitude undergoes a clear change: after Romeo saves his life, Pietro's early hostility gives way to respect and acceptance, marking his development from a skeptical worker into someone who acknowledges Romeo's character. His personal motivations are not explored in great depth, and the series does not give him any special abilities or combat skills; his importance lies mainly in how he reflects the miners' gradual shift in attitude toward Romeo. The series provides little further detail about his background beyond his status as a mine worker.
