Revolution

Kuroyukihime is reunited with Crimson Kingbolt, aka "Crikin", a Burst Linker who moved from Tokyo to Okinawa after his parents divorced. Just then, they are surprised by the mysterious threat, revealed to be a Burst Linker named Sulfur Pot, who has the power to tame "enemies". When it is mentioned that Sulfur Pot doesn't appear on the challenge list, Kuroyukihime realizes that he's from Tokyo, using a backdoor program to dive into Okinawa. As they fight, in the real world, Megumi finds Kuroyukihime, Ruka and Mana's bodies slumbering while linked up. As she reached to disconnect Kuroyukihime, she sees a vision of her younger self, urging her not to do it. Megumi then spots a spare cable and plugs into Accel World. Her avatar, Orchid Oracle, changes the landscape to an ocean, giving Kuroyukihime and her allies an advantage against Sulfur Pot. After severing control of his mount, the enemy then devours him. Kingbolt then gives Kuroyukihime the enhanced armament that Sulfur Pot used to control the enemy, figuring she may use it one day. As Kuroyukihime departs Okinawa, Ruka and Mana see her off. Kingbolt then sends her message informing her that the trail on Sulfur Pot has gone cold. Kuroyukihime can then only wonder about the mysterious faction Sulfur Pot belongs to.
