Guest's childhood friend. Her father, KEN, is a legendary Duelist known by everyone in the scene. She started dueling to surpass him. She is a striking beauty with orange eyes and slightly wavy black hair with deep blue two-tone accents, pinned back on the left side. Due to her cheerful and active image, she often wears revealing outfits that show off her midriff or legs. She is highly social and friendly with a wide circle of acquaintances. She has a very bright personality and takes good care of others. While she is cool-headed and playful, she is also incredibly competitive—a hard worker who once spent a whole week training just to challenge and defeat an opponent who had beaten her. However, she has very little courage when it comes to horror and absolutely hates anything scary.

Gender: Male Age: 18 Birthday: July 29th Height: 178cm Affiliation: Tir na nOg Deck: Youthberk The student council president of Kamiyama High School. He is a model student who excels in academics and never neglects his duties. He is deeply serious about dueling and admires the professional Duelist Guest. He is a renowned Duelist in his own right, known as a young ace among pros and a U-18 Individual Championship winner. However, his devotion to dueling has led him to a narrow-minded worldview where results are everything; he cannot understand and even criticizes those who enjoy dueling even when they lose. Because of this, he feels something akin to jealousy toward An, who enjoys dueling and is close to Guest, leading to a strained relationship between them.
