Aired on May 23, 2021

Liu and Mac begin their match, with Liu initially gaining the upper hand. Mac then unleashes a sudden, fierce counterattack known as "Mac Time," defeating Liu and becoming the new champion. Liu is hospitalized with serious injuries, prompting Yuri to express guilt to Joe about imposing her dreams on him. At home, Mac acts erratically and forcibly takes food from his son Miguel. Maya shares her concerns with Sakuma, who attributes the behavior to stress. Meanwhile, Yukiko reflects on a previous conversation with her brother, who suggested that "Mac Time" results from the negative effects of BES on the brain.
