Fuuko Kurasaki

Fuuko Kurasaki is the strategic backbone and Vice Legion Master of Nega Nebula, recognized across the Accelerated World under her Burst Linker alias 'Sky Raker'. Driven by an obsessive desire to achieve true flight, she once sacrificed her avatar's legs and withdrew into self-imposed isolation—until Haruyuki's earnest resolve reignited her will to return. A lifelong confidante of Black Lotus and a pivotal mentor who unlocked the Incarnate System for Haruyuki, she carries a deceptive duality: her outward elegance and courteous demeanor mask a ruthlessly demanding coaching style that leaves trainees utterly exhausted.
