Zuzu's bracelet

Zuzu's bracelet, known as Yuzu's bracelet (のブレスレット Yuzu no Buresuretto) in the Japanese version, is an item owned by Zuzu Boyle in the Yu-Gi-Oh! ARC-V anime.

Appearance
It is a metallic double banded bracelet which seems to have a slightly larger circumference than Zuzu's wrist. It has two pink stones set on either side of the bracelet where the bands intersect, framed by a simple rose design.

According to Zuzu's design sheets, the bracelet can be folded.

The metallic bands are reminiscent of Xyz Material when unfolded and intersecting, and Synchro Material when folded. The twin stones on either end of the bracelet resemble the Pendulum Zones, while their spiral rose patterns resemble Fusion.

Abilities
A seemingly innocuous and simple item, it has shown to have an interesting ability. It seems that if any of Yuya's dimensional counterparts approach Zuzu while she is in the presence of another of them or Yuya himself, the bracelet will warp one of them away, which is usually the one closer to her person. This includes their personal belongings, and anyone or anything they happen to be touching away, including Zuzu herself. This seems to occur automatically, regardless of the will of any of the people involved, as none of them seem to have any idea of what is happening. However, the bracelet seems to have priorities and will not warp Yuya away, even though it chose to warp Yuri away when Yugo approached him and Zuzu. So far, it seems as though the bracelet only warps away the counterpart that is physically closest to Zuzu.

Yuya's dimensional counterparts who had been warped away by the bracelet are teleported back to their own dimensions, seen when Yugo and Zuzu were both warped to Synchro Dimension, where Yugo told her that it was his homeland. However, there were exceptions to this case such as when Yuto was warped to an alley in another area of Maiami City.

The jewels on the bracelet will blink if Zuzu nears one of Yuya while accompanied by one of his counterparts. In this case neither are teleported away.

History
According to Skip Boyle, Zuzu has always owned this bracelet. Zuzu had the bracelet even as an child, and would wear it on a string around her neck.

Initially, the bracelet appeared innocuous until Zuzu met Yuto for the first time. After Silvio's Duel against him ended, the bracelet glowed with a pink light, causing Yuto to vanish. This happened on its own accord, with no input from Zuzu, who was shocked, having never seen it behave that way before. Immediately after that, Yuya showed up.

Later on, Zuzu met up with Yuto again, who had been tailing her for some time. After a confrontation between Sora Shiun'in, Masumi Kotsu, Zuzu and Yuto occured, the bracelet glowed again. Yuto vanished and, as with the previous time, Yuya showed up in short order.

The bracelet continued to do this, even when Zuzu was not aware of Yuto's presence. It activated upon Yuya's arrival and transported him to Shay's location, where the latter was Dueling Tio. Zuzu later questioned her father on the origin of the bracelet, and when he said that she'd always had it, she called him out on how nonsensical this answer was and stormed off to her room. Sora has also jokingly stated that the bracelet seemed like a sensor meant to find Yuya.

The phenomenon happened again after her first encounter with Shay. Shay was planning on Dueling Masumi Kotsu, however, upon noticing Zuzu, he mistook her for his sister, Ruri Kurosaki. Yuto, who appeared shortly after Shay challenged Masumi, knocked out his comrade just as he started getting excited, telling him that Zuzu was not Ruri. As Yuto carried Shay over his shoulder, they were quickly approached by Yaiba Todo, Dipper and Yuya, causing the bracelet to react. After the light diminished, both Yuto and Shay were gone, leaving everyone confused, with none more so than Zuzu herself, who started sobbing in frustration.

When Zuzu arrived to help Yuya in the aftermath of Yuto's Duel with Yugo, her bracelet glowed once more and teleported Yugo away.

While she was pursued by Yuri, Zuzu begged inwardly for Yuya's help, and coincidentally, Yugo showed up, causing Zuzu's bracelet to activate and teleport Yuri away. The bracelet then activated again when Yuya arrived in the area, but this time, since Zuzu was in contact with Yugo, she and Yugo were transported away.
