16 duelists, including Yuya, who passed the second round of Arc League Championship, now compete in a Battle Royal. This is a competition taking place in four battle zones, and Pendulum Cards are scattered around these Zones. At the Iceberg Zone, Zuzu and Gong duel against Halil and Olga respectively, both exchange students of LID. Over at the Volcano Zone, Yuya faces off with Taka and Nagi from the Bandit Warrior Academy in a tough 1 on 2 match, in which the latter are determined to win back the reputation of their own school...
Turn 3: Nagi
Nagi activates "Purple Shield" ( 5) and "Purple Sword" ( 11) in his Pendulum Zones. Nagi Pendulum Summons "Todoroki the Earthbolt Star" (2100/???) and "Senko the Skybolt Star" (2400/???) in Attack Position. He then activates the Pendulum Effect of "Purple Sword", increasing the ATK of his monsters by 200 ("Todoroki": 2100 → 2300, "Senko": 2400 → 2600). "Todoroki" attacks directly (Yuya: 3300 → 1000 LP). Yuya tries to get an Action Card, but Taka blocks him and takes it for himself. Taka subsequently activates the Action Card "Flame Ball", inflicting 200 damage to Yuya (Yuya: 1000 → 800 LP). "Senko" attacks directly, but Yuya activates his face-down "Performapal Pinch Helper", negating the attack and Special Summoning a "Performapal" monster with 800 or less ATK from his Deck, but its effects are negated. Yuya Special Summons "Performapal Thunderhino" (200/1800) in Defense Position. Nagi then activates the Quick-Play Spell Card, "Frontline Fusion", which allows him to Fusion Summon a Fusion Monster from his Extra Deck, using monsters from his hand or his side of the field as Fusion Materials during the Battle Phase. He fuses "Todoroki" and "Senko" from his field to Fusion Summon "Raijin the Breakbolt Star" (3000/2200) in Attack Position. "Raijin" attacks "Thunderhino", but Yuya activates the other effect of "Pinch Helper", which allows him to send it to the Graveyard and halve any battle damage either player takes from the battle. "Raijin" destroys "Thunderhino", with its effect inflicting piercing battle damage to Yuya (Yuya: 800 → 200 LP). At the End Phase, the effect of "Fujin" would inflict 500 damage to Yuya for each Warrior-Type monster on the field, but Dennis joins the Duel and activates effect of his "Performage Damage Juggler" to prevent the damage.
Turn 3: Halil
Halil draws "Pendulumstatue Red Fiend" and subsequently activates it ( 1) and "White Flower" ( 9) (after some difficulty and some help from Zuzu) in his Pendulum Zones. Halil Pendulum Summons "Red Lamp" (900/???) and "Purple Lamp" (1600/???) in Attack Position. As "Red Lamp" was Special Summoned, Halil activates its effect, which inflicts 600 damage to Zuzu (Zuzu: 4000 → 3400 LP). As "Purple Lamp" was Special Summoned, Halil activates its effect, which lets him add "Polymerization" from his Deck to his hand. He then activates it, fusing "La Jinn" and "Red Lamp" from his field to Fusion Summon "Fire Jinn the Flame Genie of the Lamp" (2400/???) in Attack Position. He activates its effect, which lets him inflict 600 damage to Zuzu (Zuzu: 3400 → 2800 LP). He then activates the Pendulum Effect of "Red Fiend", which increases the ATK of all FIRE monsters on the field by 300 ("Fire Jinn": 2400 → 2700). "Fire Jinn" attacks and destroys "Opera" (Zuzu: 2800 → 2400 LP). "Purple Lamp" attacks directly (Zuzu: 2400 → 800 LP).
Zuzu gets an Action Card, but she slides away out of control on the ice field and crashes into Olga, who is Dueling Gong. This turns their Duel into a Battle RoyalTag Duel, with Zuzu and Gong vs. Halil and Olga.
