Ryōta Takao transitioned from motorcycle street-racing to driving buses, carrying a past entangled with rough associates that sparked frequent conflicts. He remains undefeated in physical altercations, cementing his feared reputation. His perverted but well-intentioned nature manifests in mistreating an equally perverted companion. While operating buses, he recklessly prioritizes personal agendas over passenger safety or schedules, crashing into vehicles and causing extensive collateral damage. Authorities and media overlook these incidents as his destruction typically eliminates societal menaces. He once protected a woman fleeing with stolen diamonds, using an armored bus against her pursuer. His actions fuse thrill-seeking with a personal sense of justice, targeting those he deems threats.
