Maico Kato is on of the Card Professors hired by Yako Tenma in Yu-Gi-Oh! R. She is the sixth card professor encountered, Dueling and defeated by Dark Yugi. She is confined to a wheelchair.


True to her appearance, Maico acts like a kindly grandmother when encountered by Yugi. She speaks about her grandchildren a lot, even saying that when she beats Yugi, she'll be sure to buy them lots of toys. Like the other Card Professors, she's fairly confident with her own abilities as a Duelist. Still, she's shown to be very respectful to Yugi, in the end saying she enjoyed their Duel.



Her grandchildren are huge fans of Duel Monsters, and taught her to play at some point in the past.

At another unknown point, she joined the Card Professor mercenary group, and like the others, is hired by Tenma to stop Yugi's ascent of the KaibaCorp main building.

Yu-Gi-Oh! R


Maico's unique Duel Disk.

She first appears sipping tea, anticipating Yugi's arrival. He then comes across her after being unable to unlock the next door, and mistakes her for a kindly old woman. Yugi is quick asks her if she's seen a man with a Duel Disk on anywhere nearby, but she says she hasn't, and asks Yugi if he's looking for someone to Duel. She quickly reveals that she's a card professor, and says that the only way that Yugi can go on is to Duel her. She reveals her special Duel Disk, one that's implemented into her wheelchair and then Duels, and loses, to Yugi. After the Duel, she watches silently as Yugi runs off to Duel a possessed Gekko Tenma.


Maico plays a Forest-themed Beast Deck. She uses the effect of her "Deep Forest" Field Spell Card to hide her Level 4 and lower monsters from enemy attack and, when things don't go her way, she can Summon "Green Baboon, Defender of the Forest" as a last resort against an opponent.
