Ayu is a character that appears in For Honor's Singleplayer Campaign.
A proud Daimyo and an old friend of The Orochi, Ayu helped break him out of prison to help drive off the Viking raiders from the city. However, during the Blackstone Legion's raid that assassinated the Dawn Empire's emperor, she was captured and brought before Apollyon along with the other Daimyo. When Seijuro was the first Daimyo to claim the mantle as Emperor, Ayu and the other Daimyo were left in the swamps to fight each other. Ayu knew this would lead to civil war so she took out the other Daimyo before going after Seijuro. The Orochi bested Seijuro in a duel so she took the throne as Empress and had Seijuro become one of her commanders. She helped lead the charge against Apollyon's fortress.
Strong, proud, and with good reason to be, Ayu was dedicated to her people while still aspiring to become more. After killing the other Daimyo, she refused to kill their followers, knowing she had to unite them to prevent a civil war.
