The Duel Sanctuary, known as the Duel Lodge (決闘庵 Kettō an) in the Japanese version, is a dojo owned by Roku. It is located in the mountains around Heartland City. Roku carved many statues that honor famous Duel Monsters cards from previous eras. With the holographic technology of Augmented Reality, he can make the statues come to life for Statue Duels.
Some of the statues are:
- Blade Armor Ninja
- Blue-Eyes Ultimate Dragon
- Blue-Eyes White Dragon
- Cyber Dragon
- Dark Magician
- Dark Magician Girl
- Elemental Hero Flame Wingman
- Elemental Hero Neos
- Flame Swordsman
- Rainbow Dragon
- Red-Eyes Black Dragon
- Super Vehicroid - Stealth Union
Roku trains students to better themselves at Duel Monsters and other tasks. His former disciples include Kaze. Hidden within the Lodge is a powerful Deck of cards, which Roku gives to Yuma Tsukumo after the boy defeats Kaze. Although he wasn't trained there, Astral also considers himself a disciple.
- While many monsters used by powerful duelists from the second series anime and GX are present in statue form, no cards used by powerful duelists from Yu-Gi-Oh! 5D's can be found here.
