Kamen Rider 555
The older brother of Chie Morishita, whom Yuji Kiba accidentally killed in a rage after becoming the Horse Orphnoch, Morishita seeks out Kiba to help him track down his sister's killer, not knowing that he was the one who killed her, but Kiba refuses, still feeling guilty over it.
Morishita was later attacked by the Flyingfish Orphnoch, who sired him to become the Armadillo Orphnoch. After hearing people voice negative opinions about his sister, Morishita transformed into the Armadillo Orphnoch and went on a killing spree. He was soon killed by Kamen Rider Faiz a Sparkle Cut.
