Cross Heart Attack.Mayu Arita, an over-excited schoolgirl, and Harada, a member of a popular boy band, arrive at the arbiter bar run by Ginti, who has them play a game of Twister. While Mayu is excited to play with someone from her favorite band, Harada is more concerned with getting back to his girlfriend. When Mayu and Harada demand a break, Ginti changes up the game, causing the climate of the game mat to change with each different panel they step on, from heating to freezing cold. Suddenly, Mayu and Harada are put in a sudden death situation above a pit of spikes. Just as Harada is about to push Mayu off to save himself, Mayu decides to forfeit and lets herself drop. Harada grabs her, feeling guilty over driving one of his ex-girlfriends to suicide. Mayu lets go to save him but she lands safely on rubber spikes instead of dying. Mayu then remembers that she died after slipping on some soap, while Harada recalls he was killed by his girlfriend, in revenge for the suicide of her sister who was his ex-girlfriend. Later, Harada takes an interest in Mayu after she changes into a kimono, and together they perform a concert for the arbiter staff.
