Kenshiro's Fighting Spirit

With the truth about why Shin stole Yuria from him revealed, Kenshiro's rage erupts in the form of his Toki (Fighting Spirit) while Jagi is distracted by his own gloating. With a deafening battle cry and a mighty punch to the roof of the building the two are standing on, Kenshiro sends both Jagi and himself straight down into the basement where the final throes of the battle will take place.
