Scale 18

'''"Unknown Enemy!" '(未知なる敵！Michinaru Teki!) is the eighteenth chapter of Yu-Gi-Oh! ARC-V'' manga series.

Synopsis
The clash between Yūya and Reiji meets an early conclusion when Ren suddenly appears in front of them, revealing a shocking truth about the Genesis Omega Dragon.

Featured Duel: Yūya vs. Reiji
Duel continues from the previous Scale.

Turn 7: Yūya

Since Yuya has a monster in his Pendulum Zone and an "Odd-Eyes" monster in his Extra Deck, he performs an Overscale Pendulum and Pendulum Summons "Odd-Eyes Phantasma Dragon" (3000/???) from his hand regardless of his Pendulum Scales. "Phantasma" attacks "DDD Destiny King Zero Laplace", with the latter's effect activating, making its ATK double the ATK of "Phantasma" ("Zero Laplace": ATK 0 → 6000). However, the effect of "Phantasma" activates as well, reducing the ATK of "Zero Laplace" by 1000 for each Pendulum Monster in Yūya's Extra Deck upon its attack; "Odd-Eyes Persona Dragon", "Odd-Eyes Phantom Dragon" and three copies of "Entermate Card Gardna" are currently in Yūya's Extra Deck, so the ATK of "Zero Laplace" is decreased by 5000 ("Zero Laplace": ATK 6000 → 1000). The attack continues, but Reiji activates the other effect of "Zero Laplace", preventing its own destruction as well as reducing the battle damage to Reiji to zero.

Turn 8: Reiji

Reiji plays a new card on his Duel Disk, however, Ren immediately shows up, interrupting the Duel, which ends with no result.
