Trials of a King[]
Fusoya only made an appearance as he found Cecil sleeping inside the Mist Cave. He actually arrived there via spirit and drew out Cecil's spirit from his sleeping vessel and he offered him to visit his former hometown, Mist. This was the village as Golbez explained he hid himself to the borderlands at the Giant of Babil. He took him there and it was still nighttime but almost 2 decades ago! Fusoya showed Cecil his old family including his parents, Kluya and Cecilia, as well as his brother before he became Golbez, Theodor. He watched him talk to Kluya on learning magic, then he passed the next day as people took advantage of his teachings, then he witnessed his birth before his mom passed! Despite his desperate attempts to cure his parents, Fusoya reminded him he's still in the past and his healing spells will have no effect. By the time the night terror was over, Fusoya was gone, and Cecil was still inside the Mist Cave.
