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. 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. He expresses a cruel attitude towards Shu, but being a part of Daath, is implied to have some hopes in him for becoming Adam.
