Synopsis
Yūya's first Duel in the Maiami Championship finally begins! His opponent is the one who once suffered great humiliation, Shingo!! Yūya is determined not to lose, and challenges the "Yosenju" monsters with all he's got!! On the other hand, Shingo shows himself in a new "form" and by using the Yosenju monsters, his revenge scenario cannot be stopped!

Yūya Sakaki vs. Shingo Sawatari
At the start of the Duel, the Field Magic Card "Ruined Castle of the Sunset" is activated, as per the rules of an Action Duel. It will allow the players to use Action Cards, but they may only have one in their hand at a time.

Turn 1: Yūya

As he controls no monsters, Yūya Special Summons "Entermate Drumming Kong" (1600/900) from his hand in Attack Position by reducing its Level by 1, to 4. Yūya Sets a card.

Turn 2: Shingo

Shingo draws the Permanent Magic Card "Yokai Shrine of Trials" and activates it. It will gain 1 Yosen Counter every time he Normal or Special Summons a "Yosenju" monster. Shingo Normal Summons "Yosenju Kamaitachi" (1600/500). (Yosen Counter 0 → 1). As it was Normal Summoned, he activates its effect, which lets him Normal Summon another "Yosenju" monster, except "Kamaitachi". He Normal Summons "Yosenju Kamanitachi" (1800/200) (Yosen Counter 1 → 2). As it was Normal Summoned, he activates its effect, which also lets him Normal Summon another "Yosenju" monster, except "Kamanitachi". He Normal Summons "Yosenju Kamamitachi" (1500/800) (Yosen Counter 2 → 3). Shingo activates the other effect of "Kamaitachi", which lets him target a Face-up card Yūya controls and return it to the hand. He returns "Drumming Kong". "Kamaitachi" attacks directly, but Yūya activates his face-down Continuous Trap Card, "Entermate Pinch Helper", which lets him negate a direct attack and Special Summon a "Entermate" monster with 800 ATK or less from his Deck with its effects negated. He Special Summons "Entermate Kaleido Scorpion" (100/2300) in Defense Position. "Yosenju Kamanitachi" attacks directly via its own effect, but the battle damage is halved. Yūya attempts to get an Action Card, but is intercepted by the attack of "Yosenju Kamanitachi" (Yūya 4000 → 3100). Since a "Yosenju" other than "Yosenju Kamamitachi" inflicted battle damage to the opponent, Shingo activates the effect of "Kamamitachi", which lets him add a "Yosenju" card from his Deck to his hand. He adds "Yosenju Oyamabiko". He activates the effect of "Shrine of Trials", removing 3 Yosen Counters (Yosen Counter 3 → 0) to add another "Yosenju" card from his Deck to his hand. He adds "Mayosenju Daibakaze". Shingo Sets a card. During his End Phase, the effects of "Kamaitachi", "Kamanitachi" and "Kamamitachi" activate, returning them to the hand since they were Normal Summoned this turn.

Turn 3: Yūya

Yūya draws "Timegazer Magician". Yūya places "Timegazer Magician" in the left Pendulum Zone (Pendulum Scale: 8) and "Stargazer Magician" in the right Pendulum Zone (Pendulum Scale: 1). He Pendulum Summons "Entermate Drumming Kong" and "Odd-Eyes Pendulum Dragon" (2500/2000). "Odd-Eyes" attacks directly, but Shingo activates the effect of the "Yosenju Oyamabiko" in his hand, which lets him send another "Yosenju" monster from his hand to the Graveyard in order to Special Summon "Oyamabiko". He sends "Yosenju Kodama" and Special Summons "Oyamabiko" in Attack Position (Yosen Counter 0 → 1). Its ATK and DEF become equal to the original ATK of the monster who attacked ("Oyamabiko" ?/? → 2500/2500). As a monster he controls is battling, Yūya activates the effect of "Drumming Kong", targeting "Odd-Eyes" to have it gain 600 ATK ("Odd-Eyes" 2500/2000 → 3100/2000). "Odd-Eyes" destroys "Oyamabiko", and since it was a Level 5 or higher monster, the battle damage is doubled (Shingo: 4000 → 2800). Shingo activates the effect of "Oyamabiko", as it was destroyed by battle, letting him add another copy of "Oyamabiko" from his Deck to his hand.

Turn 4: Shingo

Shingo Normal Summons "Yosenju Kamaitachi" (Yosen Counter 1 → 2), activating its effect to Normal Summon "Yosenju Kamanitachi" ( Yosen Counter 2 → 3), and also activating the latter's effect to Normal Summon "Yosenju Kamamitachi" (Yosen Counter 3 → 4). The effect of "Yosenju Kamanitachi" lets it attack Yūya directly by halving the battle damage it inflicts. Yūya attempts to get an Action Card, but is intercepted by the attack of "Yosenju Kamanitachi" (Yūya: 3100 → 2200). He activates the effect of "Yosenju Kamamitachi" again, adding "Yosenju Sarenshinchu" from his Deck to his hand. He then activates the effect of "Shrine of Trials", removing 3 Yosen Counters (Yosen Counter 4 → 1) to add "Yosenju Urenshinchu" from his Deck to his hand. Shingo places "Sarenshinchu" in the right Pendulum Zone (Pendulum Scale: 5) and "Urenshinchu" in the left Pendulum Zone (Pendulum Scale: 3). He then activates the effect of "Sarenshinchu", since he has a "Yosenju" card in his other Pendulum Zone; he increases its Pendulum Scale to 11 ("Sarenshinchu" Scale 5 → 11) until the End Phase, though he can only Special Summon "Yosenju" monsters this turn. Shingo Pendulum Summons "Mayosenju Daibakaze" (3000/300) (Yosen Counter 1 → 2). He activates its effect, letting him return up to two cards on the field to the owner's hand. He targets "Timegazer Magician" and "Stargazer Magician", but before the effect resolves, since he controls "Daibakaze", he activates his face-down "Dizzying Winds of Yosen Village". When a non-"Yosenju" card would return from the field to the hand, it's shuffled into the Deck instead. Both cards resolve, thus "Timegazer Magician and Stargazer Magician" are shuffled into Yūya's Deck. Shingo activates "Yosen Whirlwind" by paying 800 Life Points (Shingo: 2800 → 2000). At the End Phase, "Kamaitachi", "Kamanitachi" and "Kamamitachi" return to the hand, triggering the effect of "Yosen Whirlwind", which lets Shingo return a card from the field to the hand every time a "Yosenju" monster he controls returns to the hand. Since three "Yosenju" returned to the hand, he chooses to return Yūya's "Kaleidoscorp", "Pinch Helper" and "Drumming Kong", and due to "Dizzying Winds", they are shuffled into the Deck instead. The effect of "Daibakaze" activates, returning itself to the hand since it was Special Summoned this turn, and thanks to "Whirlwind" and "Dizzying Winds", he shuffles "Odd-Eyes" into Yūya's Deck.

Turn 5: Yūya

Yūya Sets two cards. He moves to find an Action Card.

Duel continues in the next episode.
