Fuuko Kurasaki

A "retired" Burst Linker responsible of the wind corner of the four elements. She's Ash Roller "parent", the only person in Accel World he shows respect towards. Before Silver Crow existed she was known as 'The person closest to the sky in accelerated world' gaining the nicknames 'Astro', 'ICBM' and 'Icarus'; she became obsessed with the desire of flying, because of that she was abandoned by most of her friends and her "parent"; she gets the help of her friend and master Black Lotus to reach level 8. Having spent several level up bonus trying to obtain the ability to fly she eventually asks Black Lotus to cut off her avatar's legs to reduce her avatar's weight and increase her mind power. She is introduced to Silver Crow by Ash Roller in the Unlimited Neutral Field to help him control his mind power and use the Incarnate System to fly without his wings. As noted by Haruyuki, she has artificial legs in the real world.
