10

As Kyūtarō Ōba put his master plan in motion, he finally reveals his true colors. During a confrontation with Toshihiko, he reveals he's behind the "medicine" thats turning humans into flesh eaters and that he's been using their arms for his benefit. Toshihiko tries to fight him but he's no match for Ōba who's had more experience using the Kemonozume. It is heavily implied that he also uses Kemonozume and had Harumi's arms for the procedure. After the defeat, Toshihiko runs into Bon, who reveals to him that he is Ōba's son. He also reveals his father made him use the Kemonozume to be stronger. But he has no desire to be strong, he just wants to have friends and agrees to help Toshihiko to go and defeat his father. (Source: Wikipedia)
