Suō Yobitsugi witnessed the death of both parents in a childhood train accident, an event that resulted in severe emotional shutdown and fragmented amnesia regarding the incident. This individual was chosen to participate in the Fated Clash, a conflict revolving around six powerful cards known as the Six Desires. Selected by a Fated One card that resonated with personal desire, Suō was paired with an avatar unit from the planet Cray, an entity closely linked to their sense of self.

A forgotten connection existed between Suō and the other participants, rooted in a shared summer camp hosted by the Kiyokura Group a decade prior. These memories resurfaced only when triggered by later events. Through cardfighting and participation in the Fated Clash, Suō discovered a purpose that filled a deep emptiness, independent of the conflict’s potential wish.

After the Fated Clash, Suō continued competitive cardfighting and took part in the Destined Showdown, securing victory in the team-based competition. The bond with the celestial avatar deepened, with communication occurring through dreams and the gift of a new powerful entity named Nexus—a symbol of a stronger, renewed self. Suō later qualified for the DELUXE tournament, ranking among the top eight fighters competing to determine the strongest competitor.
