"Hanabi Iwase" is a japanese girl who loved and lived street racing, particularly the touge in the mountains of the Saitama region. She earned the title of "Dark Heart" due to her aggressive flirtatious attitude that she uses often to taunt others and her black modified Nissan Skyline R33 that she became known to utilize for several years and stuck with, particularly being one of the fastest in her area in Saitama region and one of the best uphill specialist on her joined team, the infamous "Iron Generals" composed of only the best drivers in the region of Saitama, Hanabi is unofficially often recognized to be the #3 overall best driver of the Iron Generals out of their 7 infamous members, further proving her lethality once challenged or doubted to be anywhere near racer material. As if her sheer obsession with the culture, particularly Nissan vehicles, hasn't already been noticed and even started to get annoying with her constant praise and sometimes sheer scrutiny for anything that isn't Nissan hasn't made it obvious."
