Sora, the protaganist, used to be a man named 'Azu' - Azu acted very childlike and would sometimes act in a way that a child would, but he was still one of the greatest heroes through the way he fought and won every battle with as much childlike innocence as he had started. But around his teammates, whilst holding that weird childlike personality was kinder than anyone and could instantly mature if needed at the drop of a hat. Most of his teammates had seen his rare mature side and this was the reason they followed him. When he had died he used a secret reincarnation spell and had given his teammates the mission of secretly raising him in his next life.

This is the story of how he lived his 'second chance'.
