Yomei Ichinen no Koushaku Shisoku wa, Tabi wo Shitai

Born into a ducal family, Yona 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, Yona 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, Yona made a decision: as his final wish, he would set out on a journey to seek the world's legends. Yet Yona does not know, that on this journey, he will bring about miracles wherever he goes, and come to be known as a "Little Hero." (Source: Futabasha, translated)
