At the moment Minamoto Tamako answered "I refuse," the giant screen inside Seven Sins Temple announced the end of the bet—designer Yakou Shichi won the victory.
Moriyama Yasurou loudly argued, claiming that there was a premise to their bet: Minamoto Tamako's choice would only be valid if she made it without interruption.
Yakou Shichi immediately retorted, stating that Minamoto Tamako was not subjected to what would conventionally be considered 'interference,' meaning no one threatened her life safety or physically blocked her. The latest bet clearly mentioned that the decisive factor for winning was 'Minamoto Tamako's autonomous choice.'
Moriyama Yasurou anticipated Yakou Shichi would play word games but didn't expect him to take it to such an extent.
At the moment, she had no rebuttal, nor the ability to default, and could only concede.
