Sword Art Online: Progressive

Synopsis

"This game is impossible to clear. It's just a matter of when, where and how you die." Kayaba Akihiko's death game has been up for one month. This incredibly difficult VRMMO has already claimed 2000 victims. It's the day of the 1st floor boss strategy meeting. The solo player Kirito, who's decided to only strengthen himself, meets a rare female player on the current front lines, while heading to the meeting around noon. Fighting alone against the strong monsters, she was like a meteor cutting the night sky. (Source: MyAnimeList)
