I guess we will call the game, Black Panther here instead of Black Leopard, even if the game has no official US name. We already know with the last trailer, that the lead character Tatsuya Ukyou accidentally kills Naoki Toda, a high ranking Tojo Clan member. What we did not know is that Ukyo was planning on leaving Kamurocho after the killing, but was attacked by some men that knocked him out with a stun gun.
When Ukyo was unconscious they took him to Dragon Heat, an underground fighting arena that is ran by the Tojo Clan’s Kuki family. There is a big fight going on, two fighters are going at it, Takeru and Ryu. Takeru is powerful, but loses because of Ryu’s dead on hits. Uyko is then approached by the manager, Ryutaro Kuki, telling him if he joins Dragon Heat he will overlook the death of Naoki Toda.
