A new sensation sport that melts the brain and heats the heart—KEIDOUMYAKU has arrived! KEIDOUMYAKU is a competitive sport centered on the technique of compressing the carotid arteries in the neck to restrict blood flow to the brain. This sport evaluates how an opponent collapses, exploring the mechanics behind it. Points are awarded for the expression during choking, the artistry of the moment of unconsciousness, and the precision of emergency care. Nono Akari has a soft, flexible neck that's easy to choke; when her carotid artery is compressed, she instantly rolls her eyes back and gently drifts into unconsciousness. In contrast, Hino Iori has a slender yet muscular neck—easy to grip by hand, but difficult to compress depending on the technique. She tends to convulse before fainting, often causing concern among observers. Despite the incomprehensible nature of this sport, both athletes continue competing even after fainting and waking up in confusion, a display that deeply moves the audience.
