«Lambent Light» (ランベントライト, Ranbento Raito?) was a one-handed rapier owned by Asuna in Sword Art Online (SAO). The rapier was crafted by Lisbeth as a masterpiece of a quality that she could only achieve once every three months. Asuna's rapier, combined with her speed, earned her the nickname «The Flash». The Lambent Light was boosted to +32 by Lisbeth and was Asuna's final weapon in Sword Art Online.
