The Duke’s Son, With One Year to Live, Wants to Travel (WN)

Born into a ducal family, Jonah was bedridden, his body ravaged by the vast magical power flowing within him. One day, he happened upon a book, one that contained the entirety of ancient magic. Among its pages was a spell: Magic to Manipulate Objects.

"If I can master this... maybe I'll be able to walk like a normal person..."

Through desperate effort, Jonah succeeded in learning the magic. But soon after, a doctor informed him that he only had one year left to live. Standing on the edge of despair, Jonah made a decision: as his final wish, he would set out on a journey to seek the world's legends. Yet Jonah does not know, that on this journey, he will bring about miracles wherever he goes, and come to be known as a "Little Hero."
