Konno Yuuki, the “Absolute Sword” (or “Zekken”), will be playable in Sword Art Online: Lost Song, Bandai Namco announced at the Dengeki Bunko Spring Festival in Akihabara today. She’ll be available for use from the game’s beginning.
Additionally, the company provided a first look at an additional boss planned for a post-launch update. See that below.

Finally, over at Games Talk, you can see images of the game’s crossover content with God Eater 2: Rage Burst (and vice-versa). For God Eater 2: Rage Burst, they’re releasing Kirito and Sinon costumes. For Sword Art Online: Lost Song, they’re releasing a Julius costume for Kirito, and an Alina costume for Asuna.
Watch a new trailer featuring Yuuki below.
