Accel Overdrive

Haru has the ability of flight and almost unrivaled speed. What if there was another ability that could match that? That ability is Accel Overdrive, the power to literally overdrive ones acceleration. The one who holds that ability is Kazuto Yuuki, a student at Takamatsu Highschool, but Burst Linkers know him as Navy Blade, the Burst Reaper. Pairing is OCXFuko/Sky Raker.
