Yu-Gi-Oh Zexal – A spin-off where Yuma Tsukumo teams up with a mysterious being called Astral to become a champion Duelist, competing in fast-paced and high-stakes card battles. Tori Meadows (Kotori Mizuki) is Yuma Tsukumo's childhood friend and one of the primary female characters in Yu-Gi-Oh! Zexal. She is kind-hearted, loyal, and always by Yuma's side, supporting him throughout his duels and adventures. Although Tori is not a duelist herself, she provides emotional encouragement and often serves as Yuma’s anchor, helping him stay positive during difficult times. Her relationship with Yuma reflects a deep bond of friendship, and she is fiercely protective of him. Tori is a calming presence in the series, standing by Yuma even when the stakes are high. Cathy Katherine (Cat-chan) is a quirky and energetic girl with a strong obsession for cats, which is reflected in her dueling deck that features feline-themed monsters. Cathy harbors a crush on Yuma and often gets flustered around him. Despite her comedic personality, Cathy is a competent duelist and shows remarkable growth throughout the series. Her cat-themed strategy makes her a unique and playful character, providing both humor and support to the main cast during their adventures. Rio Kastle (Rio Kamishiro) is the twin sister of Reginald "Shark" Kastle (Ryoga Kamishiro), and she has a much darker and more mysterious role compared to other female characters in Zexal. She is elegant, composed, and highly skilled as a duelist. Rio's connection to the Barian World and her importance in the larger narrative make her a pivotal character in the second half of the series. While Rio's brother plays a central role in their family dynamic, she proves to be strong-willed and capable on her own. Her development over the series highlights themes of loyalty, familial ties, and her own inner strength. Anna Kaboom (Anna Kozuki) is an energetic and explosive duelist introduced later in Zexal. She is known for her fiery personality and her unique train-themed deck, which allows her to bring heavy artillery to the field. Anna has a strong competitive streak and initially views Yuma as a rival, though she eventually becomes one of his close friends. Her boldness and aggressive dueling style add intensity and excitement to her matches, showcasing her formidable skills as a duelist who never backs down from a challenge.
