Kinoko has red hair designed in a mushroom cut, with longer hair in the back, and has bright blue eyes. She typically wears a red shirt with short blue overalls, brown sandals with white socks, and a yellow bow on top of her head.
"Kinoko" means "mushroom", referencing not only her haircut, but the fungus-based nature of her Deck.
Kinoko is the more rambunctious of the two Yudin twins, and is also somewhat of a klutz. She has a tendency to tease her friends and Sokudo, but never goes too far. Kinoko is smart for her age, much like Sokudo, from a combo of his parents' and Kohaku's support.
Kinoko shares a strong bond with her older brother Kohaku. The two often play with each other and practice their Dueling, and Kohaku helped her pick out her Deck. It is later known that Kohaku named her.
Being twins, Kinoko and Sokudo share a very close bond, even closer than Kinoko's bond with Kohaku. Kinoko often teases Sokudo, but she gets worried whenever Sokudo ignores her.
Like Kohaku and Sokudo, Kinoko enjoys watching Hakaimo while she's either asleep or awake. Hakaimo clearly knows who Kinoko is, smiling when she sees her.
- Kinoko's design and name are based off of video game character Mario, with the yellow bow of her head being derived from Princess Peach's crown.
- Kinoko and Sokudo's birthday, May 8th, is also Taylor Gorrell's birthday.
Kinoko's Deck is a Fungus Deck, focused on the use of Mold Counters and Spore Counters to control the field in combination with "Powder Cloud" Spell Cards.
