I'm Shinnosuke, the Card Master of the Ultraman World

The three protagonists grew up together in an orphanage.

During an earthquake, one transmigrates to the Mysterious Revival world and becomes Wang Shanshan, a character from the original story.

Another transmigrates to the Overlord world and becomes the princess of the Holy Kingdom.

The last transmigrates to another Blue Star world and is reincarnated as Shinnosuke.

Wang Shanshan's System lets her draw cards from the Yu-Gi-Oh! world by sacrificing "ghosts."

The Holy Princess in the Overlord world can gain control of monster cards materialized by the Yu-Gi-Oh! System by killing them.

Shinnosuke, who transmigrates to a Blue Star in the same universe as Ultraman, can navigate various secret realms to search for equipment cards.

The problem is that the monster cards powerful enough to become gods in the Yu-Gi-Oh! universe also exist in his world.

This is a story about how, whenever Shinnosuke encounters a Duel Monster he can't beat, he persuades Ultraman to team up with him.

Note: Shinnosuke is ten years old when he first appears in this book, and will grow older as time passes.
