Sword Art Online Re:Aincrad, Vol. 4 (manga)

Kirito agrees to help the young beast tamer Silica recover an item that might bring her beloved companion Pina back to life, and the pair head up to the forty-seventh floor to battle a horde of plant monsters for it. Back in a town that should be a safe zone where no one can be harmed, Kirito stumbles upon a killing that ought to be impossible. He and Asuna must work out how it happened and track down the culprit before anyone else dies.
