Accelerator is back and he’s up against a pretty tricky candidate. We never really got to see Kazuki’s super form in action for very long since the series ended basically just as he obtained the ability. With more screen time I think it would be a blow out win in his favor, but as it stands then it gets close. I think he has the speed and power needed to get around Accelerator’s vectors. Stopping his punishing attacks would be incredibly tricky and his regeneration also ends up helping him quite a lot as well. Kazuki wins.
