After countless times of seeing his Hope monster turn into a turtle, Liu Hao is chosen by a system to be transported to the Yu-Gi-Oh! world. "At least there won't be that many turtles to eat here," thinks Liu Hao, renamed You Hao by the system. But he soon discovers that this is actually the Xyz Dimension of the A5 world! And the academy's dog-walking group has already found him. Many years later, You Hao, who led the Xyz Dimension to unify the four dimensions, recounts his journey. When I saw Kurosaki Hayato sitting dejectedly in his chair, weeping inconsolably after failing to protect his sister, that image will forever be etched in my memory. At that moment, I thought to myself, if I become a duelist, I must win everything. To restore the glory of the Xyz Dimension, it is our duty.
