Sword Art Online Material Edition 09

Concerto of Black and White (黒白のコンチェルト) is the ninth Material Edition of the Sword Art Online series. Kawahara Reki published it under his pen name Kunori Fumio. It was sold at COMITIA 99 on February 5, 2012. The story features Kirito and Asuna's adventure on 3nd Floor of Aincrad. It was later expanded and published as the second volume of the Progressive series.

Part 1
After clearing the 2nd Floor boss, Kirito and Asuna made their way to the next floor. The boy explained about new monsters and how Kayaba Akihiko had considered SAO a "Concerto of life and death". While talking, they arrived at the door leading to the new floor, however Kirito didn't notice it and hit his head, falling down on a rock in just unlocked zone. After entering as well, Asuna started to admire the sylvan scenery, but she was soon interrupted by Kirito who wanted her to decide whether continue in a party or disband it. Since she strongly opposed to the latter option, the two ventured deeper into the forest.

Part 2
While wandering and talking about their current situation, Kirito and Asuna were attacked by Treant Sapling. After quickly defeating the enemy, Kirito explained that he wanted to start a quest that required fiding an NPC in a random location. They started to search for the sound of sword collding and soon were able to follow the trail, eventually spotting two elf NPCs fighting each other. Kirito informed Asuna about the procedure for starting the quest and, in order to help female Dark Elf, they attacked male Forest Elf.
