Yamato Shigure died at the age of 12. His one regret, dying without accomplishing anything in life. No friends, no love life and he rarely spent time at home because he was hospitalized, or in and out of the hospital for most of his life. As he died, he conversed with Fate. Fate asked him what he wanted.

"Do you want to be King?""I don't know. It might be fun.""What do you want?""I want the power to change my fate. I want the power to live the life I wanted!"

When he woke up, he was in another world, in another life. Yamato Shigure became Adais von Calais Emrys. The Fouth Prince of the Northern Kingdom of Calais Emrys. In this life, he was born with everything he didn't have in the previous life; a family, friends and the chance to experience love someday. The power to be king has been granted to him by Fate. The chance to fulfil his lifelong wish for adventure is here! The story of a reincarnated adventure-seeker begins!"When your soul returns, I look forward to listen to your tale. The Tale of the Explorer King."
