Biography
Mr. Tsukumo is an adventurer and the father of the Yu-Gi-Oh! ZEXAL protagonist, Yuma Tsukumo. Before setting off to the exploration of some ancient ruins with his wife, Mr. Tsukumo gave his deck to his son.

He is also the creator of Yuma's catchphrase and challenging spirit "Kattobingu". He and Yuma went on an exploration when Yuma was younger and taught him about never giving up.

In episode 19, it appears that while on the verge of death (while traversing a snowy mountain), Mr. Tsukumo encountered a being from the Astral World, similar to Astral, although it's unconfirmed if it was Astral himself. It is unknown whether or not he and his wife are currently alive.

Deck
Mr. Tsukumo played a Syllable Deck. He was only shown Dueling during one of Yuma's flashbacks. At the time he Dueled his son Yuma. After a few attacks, he tried to Xyz Summon using "Gogogo Golem" and "Ganbara Knight", but failed since he didn't have any Xyz Monsters. Later he left Yuma the Deck, which the latter began to use in place of his original Deck.
