Kazuaki Kiba

Kazuaki Kiba (木場 一彰) was the cousin of Yuji Kiba who entered a relationship with his girlfriend Chie Morishita following his death in a horrific car crash. After Yuji returned two years later, having become the Horse Orphnoch, he learned of this and lost control when he confronted the new boyfriend as he assumed his Orphnoch form to kill him in a maddened rage before realising what he had done. When he was called by Chie later, he was heartbroken when she named him the culprit in Kazuaki's murder, outrunning the police before he murdered Chie out of scorn.
