刀剑神域进击篇：无星之夜

讲述在浮游城“艾恩葛朗特”从第一层开始往上攻略的故事。

High school student Asuna struggles to survive with a young swordsman after its revealed that she is trapped inside the game of Sword Art Online, where if your HP drops to zero, your brain will be destroyed in real life.
"There's no way to beat this game. The only difference is when and where you die..." One month after Kayaba Akihiko's game of death began, the death toll continues to rise, two thousand players having already lost their lives to the ultra-difficult VRMMO world of Sword Art Online. On the day of the strategy meeting to plan out the first-floor boss battle, Kirito, a solo player who vows to fight alone to get stronger, runs into a rare, high-level female player, Asuna Yuuki. She gracefully dispatches powerful monsters with a single rapier that flashes like a shooting star in the night.
