Rin

Rin (リン Rin) is a character in the Yu-Gi-Oh! ARC-V anime. She is the Synchro Dimension counterpart of Yuzu Hīragi (from the Standard Dimension), Ruri Kurosaki (from the Xyz Dimension), and Serena (from the Fusion Dimension). Currently, Rin is in the captivity of Reo Akaba.

Appearance
Rin has shoulder length aqua green colored hair with two light green side tails and orange eyes. She wears a pair of blue studded earrings. Her outfit consist of a blue and white jacket with pink pads on the shoulders and elbows, pink shorts and white and pink boots that reach up to her thighs. Her hairstyle is also vaguely similar to Yūri with a lock of hair sticking up over her head just like Yūya. Like Yuzu, Serena and Ruri, she also wears a bracelet. When at the orphanage, she wears plain sleeveless pink shirt with a tiny deep pink ribbon on the chest area. Her Riding Duel outfit consists of a predominantly white one-piece short-sleeved jacket-miniskirt combination with light pink shoulder pads and hot pink markings, in addition to back pockets; long white gloves with light pink elbow pads that extend over her elbows, hot pink pants, and white knee-length form-fitting boots with light pink kneepads.

Personality
According to Yūgo, Rin acts a lot like mother to him. She often reprimanded him for doing things he shouldn't be doing, much like how a mother would scold her child, something that sometimes annoys Yūgo. She also always scolds Yūgo for his tendency to talk carelessly without thinking of how other people feels. Nevertheless, she is very close with Yūgo, who has feelings for her.

Etymology
Rin literally translates to "phosphorus".

History
Rin is Yūgo's childhood friend. She and Yūgo lived together in the slums of city as orphans. They were inspired by Jack Atlas and perfected their Dueling skills to later challenge him to a Riding Duel in the Friendship Cup. At one point after the invasion of the Xyz Dimension, Rin sensed that someone was following her and asked for Yūgo's help to look out for her. One night, Rin got separated from Yūgo while she was running away from her pursuer, but got cornered in the ally and was captured by Yūri.

During the Battle Royal of the Maiami Championship, Yūri mentioned that Yuzu greatly resembles Ruri and Rin. Yūgo later saw Yuzu and hugged her, mistaking her for Rin.

During Yūgo's Duel against Serena, he was confused by Serena's resemblance to her and he imagined Rin and him Dueling in the Friendship Cup.
