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.

The bracelet's flower-based design might also be inspired by "the traditional themes of natural beauty in Japanese aesthetics" (花鳥風月), with "花" (flower) representing Zuzu and her flower-themed extra deck monsters "Bloom Diva the Melodious Choir" and "Bloom Prima the Melodious Choir.

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 no matter what. If two of Yuya's counterparts excluding Yuya himself are in the same area, the one closer to Zuzu will be warped away. If Yuya enters the same area as one of his counterparts and Zuzu, that counterpart will be warped away. If there are at least three of Yuya's counterparts in the same area, including Yuya himself, the bracelet will warp all of them except Yuya away. The bracelet is capable of transporting its targets across dimensions, teleporting Zuzu and Yugo to the Synchro Dimension.

As a warning, the jewels on the bracelet will blink if Zuzu approaches any two of Yuya's counterparts, including Yuya himself, who are in close proximity to each other. The glow becomes stronger the closer they are. However, until a certain distance between them is reached, neither are teleported away.

When Yuya and all of his counterparts are synchronized and berserk, the bracelet's jewels will also blink in warning. This blinking can be used to determine where Yuya and his counterparts are.

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.

Pre-Arc League Championship
Initially, the bracelet appeared innocuous until Zuzu met Yuto for the first time. After Sylvio'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, Julia, Zuzu and Yuto occurred, 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 Herk. 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 Julia, however, upon noticing Zuzu, he mistook her for his sister, Lulu Obsidian. Yuto, who appeared shortly after Shay challenged Julia, knocked out his comrade just as he started getting excited, telling him that Zuzu was not Lulu. As Yuto carried Shay over his shoulder, they were quickly approached by Kit, 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.

Arc League Championship
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.

Friendship Cup
After arriving in the Synchro Dimension, Zuzu explained to Yugo about her bracelet and its connection to Yuya and his counterparts and her inability to control its teleportation. During the opening of the Friendship Cup, the bracelet began to resonate when Yuya entered the stadium, alerting Zuzu to Yuya's identity.

Friendship Cup Finals
During Yuya's Duel with Crow, Zuzu's and Celina's bracelets resonated when Yuya synchronized and went berserk with his counterparts simultaneously, alerting Zuzu that something might have happened to Yuya. After Yuya won the Duel, the bracelets stopped resonating, causing Zuzu to be increasingly worried about Yuya's condition.

After Zuzu escaped from the Underground Labor Facility, her bracelet started to resonate again with Celina's when Yuya, Yugo, and Yuri were in the same location with all Four Dimension Dragons out in the field and she uses it to track down Yuya's location. Upon reaching Yuya's location, her bracelet activated and transported both Yugo and Yuri away. The bracelet also sent Yuya flying but he crashed into the ceiling, forcing him out of his synchronized Berserk Mode. Her bracelet and Celina's also stopped resonating together when everything returned to normal.
