«Deadly Sins» (デッドリー・シンズ, Deddorī Shinzu?) is a 7-hit One-Handed Sword category Sword Skill in Sword Art Online, New ALfheim Online and Project Alicization.


«Deadly Sins» is activated by resting the sword on one's shoulders.[1] The skill begins with a diagonal slash from the top-right to the bottom-left, with the user making a full circle spin, drawing their sword backwards in the middle of the spin in preparation for the next attack.[2] This leads to a second diagonal slash from the bottom-right to top-left, followed by a horizontal slash from left to right. The user then executes an upward vertical slash, performing a backwards somersault.[2] This is followed by a horizontal slash from right to left and another full circle spin, which leads to a diagonal slash from the bottom-right to the top-left, stopping at face height.[2] From this position, the user spins their sword in a full circle, hitting the target from the user's right side.[2]
