Ayu Ayukawa vs. Reira Akaba
At the start of the Duel, the Field Magic Card "Mr. Sun's Canyon" 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: Ayu

Ayu Normal Summons "Aqua Actress - Guppy" (CG Star 2/600/600). She activates the Permanent Magic Card "Aquarium Stage", preventing her WATER monsters from being destroyed by battle except by other WATER monsters. She then activates the Permanent Magic Card "Aquarium Set", increasing the ATK of all "Aqua Actress" monsters on the field by 600 ("Guppy" 600 → 1200). Ayu finally activates the Permanent Magic Card "Aquarium Lighting", doubling the ATK of all "Aqua Actress" monsters until the end of the Battle Phase when they battle another monster. Ayu calls for the attack of "Guppy", but is unable since the Battle Phase can't be conducted during the first turn. Ayu Sets a card.

Turn 2: Reira

Reira activates "Persona Shutter Layer 1", targeting a monster Ayu controls and Special Summoning the former as a Normal Monster with the same name, Type, Attribute, Level, ATK, and DEF. He targets "Guppy", Summoning "Layer 1" as a copy of that card (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Reira's "Guppy" 600 → 1200). Reira Sets a card.

Turn 3: Ayu

Ayu Normal Summons "Aqua Actress - Tetra" (CG Star 1/300 → 900/300). She finds the Action Card "Mr. Sun's Energy". Ayu's "Guppy" attacks Reira's, and she activates "Mr. Sun's Energy", increasing the ATK of her "Guppy" by 400 until the end of the Battle Phase (Ayu's "Guppy" 1200 → 1600). During the Damage Step, "Aquarium Lighting" doubles the ATK of both "Guppy" (Ayu's "Guppy" 1600 → 3200, Reira's "Guppy" 1200 → 2400). Reira's "Guppy" and "Layer 1" are destroyed (Reira: 4000 → 3200 LP). "Tetra" attacks directly (Reira: 3200 → 2300 LP).

Turn 4: Reira

Reira activates the Permanent Magic Card "Persona Shutter Layer 2", preventing Ayu's cards from being affected by her own card effects (Ayu's "Guppy" 1200 → 600, Ally's "Tetra" 900 → 300). Reira activates another "Persona Shutter Layer 1", once again targeting "Guppy" and Summoning itself as a copy of the targeted monster (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Reira's "Guppy" 600 → 1200). Reira's "Guppy" attacks and destroys Ayu's "Tetra", with "Aquarium Lighting" doubling the former's ATK during the Damage Step (Reira's "Guppy" 1200 → 2400; Ally: 4000 → 1900 LP).

Turn 5: Ayu

Ayu Releases "Guppy" to Advance Summon "Aquaactress Arowana" (CG Star 6/2000/2000). Because the monster it was targeting left the field, "Layer 1" is destroyed. "Arowana" attacks directly, but Reira activates "Persona Shutter - Instant", Special Summoning it as a Normal Monster with the same name, Type, Attribute, Level, ATK, and DEF as "Arowana" (2000/2000), but it will be destroyed at the end of the Battle Phase. By the effect of "Aquarium Set", it gains 600 ATK (Reira's "Arowana" 2000 → 2600). Ally activates "Aqua Story - Urashima", banishing two "Aqua Actress" monsters from her Graveyard to turn the ATK of one of Reira's monsters into 100 and preventing its ATK from being changed by other effects until the end of the turn. She banishes "Guppy" and "Tetra" and targets Reira's "Arowana" (2600 → 100). Reira's "Arowana" and "Instant" are destroyed (Reira: 2300 → 400 LP).

Turn 6: Reira

Reira Normal Summons "CC One-Eyed Past Eye" (CG Star 3, 3/1400/1000). He then activates the Permanent Magic Card "Montage Fusion", allowing him to Fusion Summon a Fusion Monster in his Extra Deck as long as both him and his opponent control the required Fusion Material Monsters. Since Ally controls a WATER monster, he uses his "CC One-Eyed Past Eye" to Fusion Summon "CCC Water Sword the Embodiment of Valiant Fused Arms" (CG Star 6, 6/2400/???). "Water Sword" attacks and destroys "Arowana", with its effect increasing its ATK by the ATK of all other WATER monsters on the field ("Water Sword" 2400 → 4400; Ayu: 1900 → 0 LP).
