Yu-Gi-Oh Arc-V: The Dragons Overlord

A year ago, a young boy woke up in an alleyway of Maiami City without memory of his past. The only memento of his past is his Deck. A year past Himeya Shinobu armed with his Deck full of Dragons decided to become the strongest duelist and enter the Maiami Championships, hoping to find out more about his past and answer why he lost his memories in the first place.
