Marin

Marin's History

Known as Marin, she was once the priestess as well as the princess of the United Lands of the Poseidon Ocean alongside her brother, Nash. One day, the kingdom was attacked by Vector, who led a fleet of ships and several "Gorgonic Guardians" to lay waste to it and loot it.[18] After Nash led the kingdoms forces to defeat the "Gorgonic Guardians" with mirror shields, Vector performed a blood sacrifice to the ocean god, Abyss, turning the battle back into his favor. Marin rode up to Abyss and was grabbed. She offered herself as a sacrifice, plunging into the ocean depths to revive another god.[19] This action was due to Don Thousand hypnotizing her. As she owned a card called "Number 94: Crystalzero", Thousand influenced her death to aide in his own revival.[20]

Nash's and Marin's souls being transferred to the bodies of original Reginald and Rio.

An unknown number of years later, Don Thousand reincarnated both her and her brother as two of the Seven Barian Emperors, as their souls were each connected to a Mythyrian "Number" card, which had sealed Thousand's power.[21] The two became the leaders of the Seven Barian Emperors. Vector had also been reborn as a Barian Emperor and often clashed with Nash's leadership. After Nash had annoyed him enough to score 100,000,000 points on his self-made point system, Vector took Marin hostage. When Nash intervened, Vector used "Giant Sky Sword" to freeze Nash's body and force both of them to jump off a cliff.[22] Vector believed them dead[19], while Dumon believed they had vanished and assumed leadership of the group from them in the interim.[23] The two were rescued by Abyss, who informed them that he would send them to Earth, where their souls would find new bodies to inhabit. The process would eliminate their memories though until they reunited with Abyss again. Their souls were transferred to the bodies of Reginald and Rio Kastle, who had recently died in a car accident.[22]

At another time, Rio and Reginald visited a theme park where the former offered the latter one of two rings which they both could wear. Reginald initially refused to wear his ring, causing Rio to throw them on the ground and walk away in anger.[24]

Rio's state after her Duel with Quattro.

Rio once Dueled Quattro who was operating under the orders of Vetrix. He played the Spell Card, "Flaming Hell Blessing", which set the surrounding area on fire. She was critically injured in the blaze, though Quattro carried her to safety, his face being scarred in the process.[25] After this, Reginald began wearing both of the rings from their childhood to remind himself of her.[24]

In order to help his sister, Reginald entered the National Duel Circuit and made it to the final match against Quattro. In the break room, Quattro set his Deck up to fall on the floor, causing Reginald to see some of its contents. This caused him to be disqualified.[26][27]
