Iro

"Iry" (アイリ Airi) is one of Kazuo's friends in Five.

He is a card designer and illustrator with many smaller jobs around, but mostly involved with card arts for Yu-Gi-Oh! cards. He designed the "Dreamer" archetype as a shout out to his friend Kazuo, and ends up involved in the events of the Captivity arc. "Iry" is his stage name.

Dreamer
A Deck inspired on Kazuo, which will trigger him once he sees it (and thus trigger some development).

The Deck consists of "Dreamer" Main Deck monsters (regular people) who are used as materials to Summon Link-1 "Star" Link Monsters (rock star and-the-such versions of the "Dreamer" monsters). It's a Link-1 centered deck which becomes stronger gathering more low-Link monsters rather than fewer high-Link ones.
