Yugi befriends Imori, a shy kid who's been bullied, but possesses the rare Dragon Cards from China. Later the same bullies knock the Dragon Block out of Imori's hands, breaking the seal. The thug challenges Imori to a game of Dragon Block and Imori wins. This causes Imori's soul to be corrupted by thoughts of power and revenge against those who have bullied him.
He challenges Yugi to Dragon Block and wins, causing Yugi's soul to be sealed away, where it will be eaten. Dark Yugi emerges and beats Imori at Dragon Block thus freeing Yugi's soul. Only the dark side of Imori's soul is sealed away, leaving the good Imori saved from the Dragon Block's dragons. Imori then asks Yugi to help him hide the Dragon Block back into its original spot before his father comes home.
This episode contains examples of:
- Adaptational Heroism: Imori was a creepy brat who deliberately fed people to the Dragon Card in the manga, but here is corrupted by the cards' powers.
- Near-Villain Victory: By taking Yugi's soul, Imori would've been victorious in his heinous scheme to destroy the world, had Yugi not grabbed his own puzzle necklace at the last second to invoke Dark Yugi.
- Spared By Adaptation: Unlike the manga, when Imori’s soul is sealed by the game, in the anime only his evil half is taken, while the boy not only survives but asks Yami Yugi to put the game in the hidden place again.
