Shigure is the son of Azura who inherited her beautiful singing voice. He is also the biological grandson of Arete. Like other children in Fates, Shigure was raised in his own Deeprealm world where he made many friends. Unfortunately, his happiness was broken when Vallite soldiers attacked his Deeprealm, forcing him to flee. In his Paralogue, Shigure is fleeing the Vallites when he crashes onto a ship that Corrin and their allies were on. Azura is surprised to see him here, but he tells her that strange warriors had been pursuing him from his Deeprealm. Azura is surprised that they are also targeting him, while Shigure is unaware about his mother's powers and the past. Two large ships broadside theirs in the process. Shigure asks Azura if he may fight so that he may avenge his friends, but Azura refuses to let him and asks him to hide somewhere, much to his disappointment. After the battle, Azura tells him that she went to his Deeprealm to find the village destroyed and its inhabitants killed. Shigure sings Lost in Thoughts All Alone as a requiem for his fallen friends. He then asks her if he may join them, having no where else to go. She initially rejects his offer, but changes her mind so that she may protect him. If unmarried, his ending mentions that following the war he served the Hoshidan government's administration for the rest of his life.
