Background

 

This story takes place on the 48th floor where Kirito goes to the store to get a kirito sword with power equivalent to kirito current sword "Elucidator", but broke one of the Lisbeth customized sword while tested. Also you can get a kirito costume.

Lisbeth says she could make a quality sword if she had the necessary materials. Then Kirito and Lisbeth went to hunt a dragon for the "Crystalite Ignot" which is a rare metal that grows inside the stomach of the dragon, but ended up falling into a hole - the dragon nest, and in there they discovered the Crystal is actually the dragon's shit, After spending the night, the nocturnal dragon returns, and Kirito grabs Liz and they ride the dragon out of the pit.

 

After returning to the store on the 48th floor Lisbeth used the rare metal to create the "Dark Repulser."

 

Kirito has Lisbeth raise the reinforcement of Dark Repulser from +39 to +40. Reinforcement can only be obtained within 10 hits. Unfortunately for her, Kirito promptly requests for his other sword, Elucidator, to be raised to +40 as well, to which she lets out a long sigh.

 

Kirito used the " Dual Blades " skill for the first time during the 74th floor major boss (The Blue-Eyed Demon) fight.
