Romeo's best friend. He dislikes fighting, is often the voice of reason for Romeo, and is one of the few people who cares about Romeo's well-being. He and his family are later stripped of their nobility and go into hiding with the help of Juliet and her friends. Because of his status as a noble, he also has little experience with manual labor, and Curio gives him shelter rather reluctantly. He later tells Romeo about the assassination attempt and tells him he'll be waiting for the day he becomes the Duke who'll save Neo Verona. He also takes care of Curio's house after he runs away, giving shelter to Cordelia and (apparently) Antonio after the assassination fiasco. At first Cordelia treated him somewhat like a child because of how he was unable to do menial work due to his lack of experience, despite that it seems she's developing feelings for him. The couple happily wed and later have a child by the end of the series.
Juliet's best friend since childhood and another survivor of the Capulet massacre (along with Curio and Francisco, her relatives worked as Capulet vassals and died in the slaughter along with their masters), she has helped take care of Juliet since then and also acts as her private confidante. Juliet relates that the reason why she kept her hair long -rather than cut it for an easier boy-like appearance- was because Cordelia liked it that way as servants often can't relish the luxury of cosmetics. She has been hinted to have feelings for Romeo's friend, Benvolio, and agrees to marry him later in the series. She hands her wedding bouquet to Juliet, wishing for her friend's and Romeo's happiness. At the end of the series, she and Benvolio have a child.
Regan is the grand daughter of Balthasar, the servant of the Farnese family.
Childhood friend of Curio and the more intellectual of the duo. He believes that Juliet is being protected by Neo Verona itself and is himself a ladies' man who enjoys teasing the more reserved Curio. He is an expert at archery and other various thrown weapons. Sneaky and sly, he managed to contact Tybalt so he could take Juliet to safety when the Montague faction discovered their hideout. He escapes and later joins Curio to rescue Juliet from Montague. Out of all of Juliet's comrades, he is the one who openly vouches for Romeo's love for Juliet. Curio later suspects if Francisco has concealed feelings for Juliet, but he dodged the questions by affirming his loyalty to the Capulets. During their later night assault against one of the enemy posts, he confesses to having "friends" with information. Along with Curio, he assisted clearing a Romeo path to the crumbling Escalus. Years later, he shown again as an active member of Neo Verona's parliament. (Source: Wikipedia)

A mysterious warrior who aids the Capulet retainers, he tells them about the planned assassination of Benvolio's family and later aids them on his own ryuuba mounted in war gear. It is later revealed that he has a network of paid spies and informants throughout Neo Verona and that he has no qualms about killing. Tybalt is also one of the few outside the circle of Capulet retainers who knows both Juliet's secret as the last of the Capulets and her persona as the Red Whirlwind. Conrad may know the true scope of Tybalt's identity, but is still unsure. Tybalt's mother was tricked by Romeo's father, who abandoned her when he got her pregnant and married Romeo's mother. That means Tybalt is Montague illegitimate son/Romeo's half brother. For his mother's sake, he has sworn to hate and avenge her by killing the Grand Duke of the Montague family.
