Itto Fukunaga

Itto is Koji's best friend in Five.

Deck
Itto runs a WATER Deck, featuring WATER Fish Main Deck Monsters and WATER Machine Extra Deck Monsters - all based on watercrafts. His Deck's design mirrors Koji's - which's composed of WIND Beasts and WIND Machines - also featuring Metalmorph-themed cards.

His strategy consists of manipulating "Torrential" Trap Cards without actually Setting them to control the field, so that they can't be sealed or destroyed by the opponent.
