Yu-Gi-Oh!: Rebirth in the Next World

An overworked middle-aged man led a dull life, going between just two places every day. Then an unexpected incident drew him into the transmigration of Yu-Gi-Oh! spirits, causing his body to disintegrate.

However, his soul merged with a treasure held by one of the spirits.

As his soul drifted onward, he unexpectedly transmigrated into the body of a fifteen-year-old cross-dressing boy whose soul had been consumed by darkness.

From then on, the overworked middle-aged man took the boy's place and lived as a fifteen-year-old cross-dresser.

The world he transmigrated to was the world of Yu-Gi-Oh!, where card games reigned supreme.

The spirit he had encountered by chance accompanied him as he began a new life in this new world.
