Yusaka Kurose was a Hero, then a King.

Once revered as the greatest hero in history, Yusaka later forged the most powerful kingdom the world had ever known. He was utterly powerful—one could call his strength absurd. No enemy could oppose him. He was the one who people defined as an epitome of the strongest. Yet, after a mysterious event in his life, something shattered inside him. Years of living later, Yusaka decided to abandon everything and chose to reincarnate to live into the future, or either to escape his reality.

Reborn into a peaceful family, Yusaka realizes he had forgotten his past, he could vaguely remember about his memories. He chose to leave them away, hoping to live a life in tranquility in the future.

But the world felt different to him. The history he could vaguely remember had changed, truths were hidden.

But Yusaka had a question for himself.

What truly happened five hundred years ago that drove him to abandon his life?
