Main Characters
Yukiko Aiko

The main protagonist of the series who attends the New Duel Academy to become the first Queen of Games. Yukiko has a strong, tomboyish, and energetic personality that gets her heart pumping in a duel, but is shown to love cute, cool, and colorful things such as stuffed toys, flowers, and animals, has an appetite for sweets like the Sweet Duel Cafe's cakes, and has great artistic skills as she can be seen sketching under a tree when she is not dueling. She also keeps a schedule for her after school activities that involves studying, running, shopping, and taking care of her spirit partner. When attending the Fusion dueling class, Yukiko is shown to have a crush on her Fusion professor who is the head of the Fusion dorm, Jaden Yuki, because of his brooding and cynical looks and his smile. Her ace monster is the Angelic Heart Witch and her spirit partner is the Performapal Whim Witch (which is a gift from her former owner, Yuya Sakaki the professor of Pendulum dueling and head of the Pendulum dorm). In Season 1, Episode 7, she becomes the school representative after dueling her rival, Janet Black.

Selena Pureflood/Cho Emiko

A shy and kindhearted duelist who is Yukiko's best friend and spends her time reading and studying rather than dueling. She is shown to have difficulties with social people, until she meets Crystal, who helps her out of her shell and encourages her to give dueling a try. Her deck contains butterfly-themed monsters, spells, and traps.

Karen Fiery/Akako Daitan

A red haired Fusion duelist with a short temper but a big heart who is an expert at Fusion as well as Jaden Yuki, who she looks up to since seeing his duels from Duel Academy on TV when she was a child. She is an athletic girl that won five gold medals in a row during the Olympics and held the record for longest running distance. Her deck contains fire-type monsters, spells, and traps.

Janet Black/Asuka Arisu

An arrogant jet black haired girl with a deck that holds dark-type Fiend monsters, spells, and traps that can easily scare her opponents, but not Yukikio Aiko, who was attempted to duel her when she saw Selena getting picked on by her and her friends. She is shown to belong to a rich family that pushes her too hard to become the Queen of Games, but Yukiko stood up for her when she lost in another duel against her and soon, starts to slowly warm up to her, despite having to hide it with a snarky expression.

Percy Bud/Eichi Botan

A good looking and smart tolerant boy who knows about different types of plants, flowers, and trees and has a knack for animals. He is shown to have a crush on Yukiko because of her way of sticking up for others and for her heart pumping determination. As a child, he lived with his mother who taught him about the ways of nature and gifted him his first plant card, the Botanical Lion, who is his spirit partner. Like Yukiko, Percy has the ability to see and hear Duel Monster Spirits.

Mindy Lucksworth/Lala Hana

A former student of Paradox Prep who was sent to spy on Yukiko and the other students of New Duel Academy, but then turned her back on her school after becoming friends with her and helping her defend the school from other spies that were sent to spy and steal New Duel Academy's new invention plans.
