Yuu is the true main antagonist of Guilty Crown. He is a member of Da'ath, given the title "The Envoy of Da'ath". It was shown in episode 11 that he also possesses the Power of Kings like Shu. He works with Shuichiro into reviving Mana because when she matures into Eve she can form a new race with Shu who is her Adam, the person she chose to marry.
He wears a long white collared coat with a black shirt and pants. Yuu has light blond hair and icy blue eyes. He looks the same age as from Guilty Crown: Lost Christmas.
Yuu has a cold personality, and is implied to be looking down upon Shuichiro, who collaborates with him on his way to revive Eve. He expresses a cruel attitude towards Shu, but being a part of Daath, is implied to have some hopes in him for becoming Adam.
Not much of him and Da'ath is known in history, the only known facts about Yuu is that he is the organization's living incarnation, envoy for short, and that he seeks to bring in the apocalypse and have the Adam and Eve to recreate the human race.
In Episode 20, Yuu makes his introduction to Keido and Kurosu in the past explaining that Da'ath is the cause of the Apocalypse Virus Meteorite that infects Mana, and desires the Fourth Apocalypse for their goal.
Yuu makes his first appearance in Episode 6, where he thanks Keido and gives the omen that the queen of Cocytus will be awaken.
He makes a cameo in Episode 10 where he observes the second Lost Christmas.
He then appears at the end of Episode 11 where he kidnaps Inori and uses her void to attempt killing Shu, only for Gai to take the hit.
In Episode 12, Gai refers to Yuu as Da'ath's 'grave keeper' as he plans to arrange Keido and Inori into marriage so that Mana can be awoken. However, Shu and Gai foil Yuu's plan and the envoy knocks Keido unconscious for his failures.
He makes another cameo in Episode 16 where he appears in the debris of Loop 7, finding one of the meteorite rings. He also has a cameo appearance in Episode 17 to give the revived Gai his utilization of becoming king. He makes another cameo in Episodes 18 & 19 where Gai uses his void to trap and capture Inori.
Yuu makes his final appearance in Episode 21, where a flashback shows his conversation with Gai upon his revival. Then, Gai uses his, Arisa's, and Kenji's voids combined to form a void bow in shooting Apocalypse Virus crystals. Then, Yuu explains to Shu about how he is Da'ath's envoy and questions about his role as Adam and king. When Shu refuses, Yuu tells him that Gai's answer is different, and for that, Yuu is going to strip Shu's title of the successor's throne in battle. After a brief duel with Yuu using a variety of voids from Da'ath agents, Shu uses a tri-blaster void to defeat him. Yuu then disappears and lets Shu meet with Gai.
As of now, Yuu and Da'ath's status remains unknown since the anime ended.
Like Shu (later Gai) and Scrooge, Yuu possesses the first Power of Kings, which allows him to draw out a person's Void, as shown in episode 11 when he tried to use Inori's Void to kill him. Like Gai, he apparently draws out Voids without physical or eye contact, probably because of the equipment of the soldiers on their faces that covers their eyes and projects the face of Gai or Yuu to make them think that they are making eye contact with Gai/Yuu.
In episode 21 he showed his powers extensively, using multiple Voids of several Da'ath followers gathered there to fight Shu. He showed skill in dual wielding several Voids such as dual whips, swords and chakrams, discarding them at a whim. Like Shu and Gai, he can combine Voids to produce more powerful ones, as shown when he combined dozens of Voids to produce a large double barrel cannon to kill Shu.
His own Void manifests as a large bow, that can fire high speed arrows. When the arrow hits the intended target, it produces a series of metallic stripes that can completly bind the target.
Beyond his use of the Void Genome, Yuu also showed several abilities no other character has shown so far. He has displayed the ability of levitation in several of his appearances and the ability to render a person unconscious with a touch to the forehead as shown in episode 12, when he puts Shuichiro to sleep after informing him of his failure.
In episode 21, he displayed telekinetic abilities by stopping and redirecting a flurry of bullets by Argo as well as the ability to create energy shields and the ability to dematerialize and materialize at will from one place to another.
- In episode 20, Yuu is shown to be standing behind a young, five year old Mana when she was playing with virus crystals on the roof of a building, most probably guiding her about her powers.
- Yuu was the one who informed Shuichiro Keido and Kurosu Ouma about Mana's crystallising powers.
- In his official artwork he seems to wear shoes, however in the series he is only seen in sandals.
- We know that he is at least 1000 years old, because in the german dub, he states that "the illusion of comradery has proven itself over the last thousand years".
