A flamboyant playwright whose works have not been well-received by audiences. He's nicknamed "Willy" by his actors and stagehands; although he often nags at them, he himself is not very punctual at completing his scripts. The character itself is a caricature of William Shakespeare, and there are several allusions to the work of his namesake in his own plays. His mother is the prestigious noblewoman Ariel, leader of the Farnese Clan. He was instrumental for building public awareness to the Red Whirlwind's revival as he authored and mentored the resistance members to re-enact Juliet's story. The audience gained empathy for her plight and were more than willing to join her because of it.

William's theater also serves as home and hideout for Juliet and her companions; according to him, one of the reasons why he accepted this task was his wish to write a wonderful blood-stained tragedy, with the Capulets as a part of his inspiration. He also knows that Juliet is deeply and painfully in love, calling her "the maiden who gave up on love" and wants to make a tragedy where both lovers die, which not only causes Juliet to tense up but also refers to the play. Years after the conflict has ended, he reflects that the lesson he learned through his observations of Juliet and Romeo was truly the joy of love.
