During the final oath duel, Mukan Youling, who should have been erased, survived thanks to his liege's protection. As the price, fragments of his memories and fantasies were scattered, and he must find a way back to the Celestial Realm while living among humans.
He encounters all kinds of people and events in the human world. Once the fragments are restored and he returns to the Celestial Realm, a huge challenge will still await him.
This book uses the rules of Yu-Gi-Oh! More than half of the decks are entirely original. The author also created a new summoning method, Contract Summoning, which was refined by a classmate. The special dueling formats are "Oath Duels" and "Spatial Duels."
Come and enter an entirely new world of dueling!
