Trading Game
by PandoraJail is a Yu-Gi-Oh! ARC-V fic that follows the story of Yuuna, a 28-year-old office lady who has been reincarnated into the body of a young orphan in the Fusion Dimension, and her personal quest to radically shift the stagnant meta of the local setting while simultaneously juggling with plans to subvert Academia's canon invasion of the other neighboring dimensions.
"When you get reincarnated in another world where the main entertainment and also the source of all human suffering is a card game, what do you do? Why sell them of course! DP is needed to actually buy food after all, and what better way to use the shop system than to sell them on retail in a much higher price? Because that's exactly what she's doing!"

Trading Game provides examples of:
- Action Girl: Yuuna and Mei certainly qualify for this, as presumably other members of the female cast.
- Anachronic Order: In some chapters, the fic shows Yuuna already exploring the other dimensions while farming for DP and getting new cards through her system, selling her old cards, and meeting other characters native to the dimension she's currently in, before diving back into her time at the orphanage and Duel Academia.
- Breaking the Fellowship: Following the 'conclusion' of her duel with the Professor in chapter 26, Yuuna was forcefully separated from her circle of friends after the man teleported her away from him in order to prevent himself from suffering an official loss on live channels.
- Cool Big Sis: Yuuna serves as this for Mei and many of the orphans of the Fusion Dimension. She later becomes this for Serena and Yuri when attending Duel Academia.
- Defeat Means Friendship:
- Subverted with Yuuna's first established rival, Haru, who became increasingly unhinged with the long streak of losses he experienced against both Yuuna and Mei.
- Played straight with other characters, such as Edo, Ryo, Serena, and Yuri.
- Discard and Draw: Yuuna frequently changes her deck throughout the story as she gradually unlocks new card packs in her shop system. The system also further enforces this trope; it locks her out of any summoning mechanic not native to the dimension she's currently residing in, which necessitates her to craft a new deck from scratch.
- The Dreaded: Yuuna received this reputation after she nearly defeated the Professor during her rampage across Academia. Even when their duel had ended on an inconclusive state due to the Professor forcefully teleporting her away before she can land the final blow, most of the common foot soldiers of Academia's invasion force continue to fear the idea of potentially encountering Yuuna again on the field.
- Guile Heroine: Yuuna's capable of coming up with certain excuses of why she had access to cards that aren't in the Fusion Dimension's database, along with being able to interact with her mentally younger peers. It helps that she also had a degree in Child Psychology in her previous life, and worked in a "black" company.
- Legacy Character: A few characters from other previous series appear in this fic, including ones that did not originally appear in the ARC-V anime. As of present, that list includes Cronos de Medici, "Kaiser" Ryo Marufuji, Fubuki Tenjoin/Nightshroud, Mr. Heartland, Kagemaru, Anna Kozuki and Haruto Tenjo.
- Reincarnate in Another World: In her previous life, Yuuna was a 28-year-old office lady of an unknown nationality who later reincarnates into the body of Yuuna, an orphan girl of the Fusion Dimension in ARC-V.
