Inoso is a parody of Roland (who is known as Isono in Japan) who appears in the Tag Force series. He is the right-hand man of Emperor.Umiuma, and works for UmiumaCorp.

In Yu-Gi-Oh! GX Tag Force, he arrives on the island alongside Umiuma and Mokuma after the player has completed the game with three of the originally available characters as a partner. He requests the player's aide in UmiumaCorp's feud with Sanzyudai Yuki. Should the player agree, he and his companions can be selected as partners for the Tag Force tournament.

DeckEdit

In Yu-Gi-Oh! GX Tag Force, Inoso plays a Skull Servant Deck aptly called Skull Servant Deck. In addition to the aforementioned series, supported by cards that send them to the Graveyard, such as "Magical Merchant" and "Card Destruction". He also includes "Chaos Necromancer", which can take advantage of the aforementioned effects.

He is one of the few duelists in the game to utilize a Side Deck, though his only contains two copies of "Great Spirit".

In later instalments he uses a Rock deck.
