The exciting part starts at 1:13 in the video. Dora (Rei) misses a wake-up DP. Amiba (Kenshiro) could punish it with his Fatal KO and win immediately. Instead, he punishes it with a super -- Hokuto Zankai Ken -- that gives Dora exactly 30 seconds to win the round, otherwise his character will die.
The countdown is in the lower-left. Each 1/10th of a second on the countdown is 1 real second.
