In his entire life, Rion had never felt happy. He didn't even remember smiling or laughing. When he decided to end it all, he lost his life. Surprisingly, he didn't feel angry. Instead, he felt free for the first time. Instead of going to the afterlife, Rion woke up in another world full of magic. He even had a new name, Arion. This time he had parents who loved him and siblings who adored him. Finally, he could feel true happiness. However, trouble doesn't leave Arion alone. There was a group that wanted to eliminate magic users, especially those from great kingdoms. His family was one of their targets. Somehow, Arion was connected to the mysterious power of a long-lost kingdom. The power symbolizes the past and the future. That makes him the main target of everyone. Both from his side and from the enemy's side. Because that's how much power he's got. “The greater the power gained, the heavier the burden to be carried.” He is the chosen one. Chosen as a human being loved and protected by the gods. And as the holder of the greatest power, with the fate of the world on his shoulders.
