A Deletion Duel, known as a PK Duel (Player Killer Duel) in the Japanese version, is a term used in the Yu-Gi-Oh! VRAINS anime to describe a Duel where the loser's LINK VRAINS account is erased, preventing them from logging into LINK VRAINS again.
This type of Duel was only seen once in the series, when The Shepherd Dueled Ghost Gal, applying the rules to a Speed Duel. The Shepherd won the Duel, but after Ghost Gal told him how their father had asked her to look out for him after he passed away, he spared Ghost Gal's account from deletion.
