«Dark Repulser» (ダークリパルサー, Dāku Riparusā?) was a one-handed long sword, created by Lisbeth for Kirito out of a Crystallite Ingot, which was obtained from a special quest. Whenever Kirito used the «Dual Blades» skill, he wielded it alongside «Elucidator». This weapon was destroyed during the fight with Heathcliff on the 75th Floor.


Dark Repulser is described in the light novels as a pale, one-handed straight sword that is slightly transparent. Its blade is white and slender, though not to the extent of a rapier. The grip is silver, with a slight tinge of blue.[1]

In the anime, Dark Repulser is aqua-colored. Its grip is a darker color than the rest of the blade and is completely straight. It leads up to a crossguard that is exactly perpendicular to the grip and is designed to look like a pair of conjoined dagger blades. At the center of the guard is a large aquamarine gem. The blade itself is a deep aqua color, the base of the blade has a light-aqua attachment that causes the blade to have a natural indentation when one traces its length due to the angle that the attachment bends at.[2]

Warmth of the Heart

The Ingot used to make the Dark Repulser.

After breaking one of Lisbeth's most prized swords, Kirito and Lisbeth set out to obtain a Crystalline Ingot on a quest on June 25, 2024. Far away on the West Mountain on the 55th Floor, there was a dragon that was rumored to produce a rare mineral. After being pushed into the pit and spending the night there, Kirito and Lisbeth found the special ingot, which was actually the dragon's excrement, but were stuck until Kirito managed to grab onto the tail of the dragon, who had returned to its nest for the day. After getting back to Lisbeth's shop, Dark Repulser was forged on June 26. Kirito swung the sword to test its weight and remarked it as "heavy", deeming the sword worthy. Kirito then demonstrated his Dual Blades skill upon Lisbeth's inquiry as to having a similar blade to his Elucidator.

Sound of Water, Sound of Hammer

In August 2024, Kirito had Lisbeth raise the reinforcement of Dark Repulser from +39 to +40. Lisbeth, although nervous, took on the challenge and, after boosting the success rate of the reinforcement to the maximum, began the ten hits with the hammer on the sword required to complete the reinforcement. Lisbeth was hesitant to perform the last hit to improve it, but Kirito told her that he felt as if he was going to wield this sword against the final boss because of the name that the system gave to the sword. Lisbeth believed those words and managed to finish the enhancement successfully. She then claimed to not have to go through such a stressful enhancement again.

Unfortunately for her, Kirito promptly requested for his other sword, Elucidator, to be raised to +40 as well, to which she let out a long sigh.

October, 2024

On October 18, 2024, Kirito was forced to use the Dark Repulser, alongside the Elucidator, to defeat The Gleam Eyes in the 74th Floor Labyrinth in order to protect an Aincrad Liberation Force party from being decimated by the Floor Boss. Two days later on October 20, the Black Swordsman used the Dark Repulser with the Elucidator in his duel against Heathcliff in Collinia but lost.

November, 2024

On November 7, 2024, Kirito utilized the Dark Repulser, along with the Elucidator, in the battle against The Skull Reaper in the 75th Floor boss room. Shortly thereafter, the swordsman wielded both blades in his fight against Heathcliff, who was revealed to be Kayaba Akihiko. At the end of a Sword Skill Kirito unleashed against the guild leader in the middle of the duel, the Dark Repulser shattered against Heathcliff's shield.

Ordinal Scale

On April 29, 2026, during the battle against An Incarnation of the Radius, the Dark Repulser and the Elucidator were loaded with the rest of the save data for Kirito's avatar from the SAO server by Yui. The two swords were used by Kirito to perform Starburst Stream as the final attack on the boss.
