Yagami held the kunai upside down and drove it down through Mei's skull.
Since he could not bring himself to ruthlessly kill Kyouko, he had to ruthlessly kill her younger sister.
In truth, Yagami had plenty of chances to prevent Kyouko from being severely wounded by her sister.
But he had done nothing. He had been waiting all along.
Only at the very last moment, when her sister was about to kill her, did he rush out and stop the murder.
