Yuya's pendant

The Pendant, also known as the Mysterious Duel Charm, is an item that belongs to Yuya Sakaki in the Yu-Gi-Oh! ARC-V anime.

The Pendant appears to be connected to Pendulum Monsters, as it changed the three Effect Monsters in Yuya's hand ("Stargazer Magician", "Timegazer Magician" and "Odd-Eyes Dragon") to Pendulum Monsters, as well as several of Yuya's other monsters.

When Yuya Pendulum Summons, a giant version of this pendant appears, swinging back and forward between the two Pendulum Zones. This is unique to Yuya. Instances of others performing a Pendulum Summon do not feature this.
