Doragon! Muteki no ken to tate - S1-E4
Other mistake: Tatsumi suggests to stop the fight because if the contestants get seriously hurt, it would reflect poorly on the Graude Foundation, but the speaker of the tournament announced just in the earlier episode that fights can end in a contestant's death. Bit late to worry about PR issues, when it's already marketed as a fight to the death. (00:19:15)
