Mariya wakes up from a vision she had about a sinister man and Liliana, but keeps it to herself hoping it was a dream and not a vision. In school, she is challenged by Erica to a baseball match resulting in indescribable suffering for Godou. Soon after Erica gives her an even bigger challenge, to buy a cellphone with Godou. For the innocent Yuri this means not only going out with a Devil King, but going out shopping with a boy for the first time in her life. That night, Godou is called by Salvatore Doni who wants Godou to fight Sasha Dejanstahl Voban, a campione who came into Japan, and become stronger. However, Godou hangs up in the middle of the call. Mariya on the other hand, has her bath rudely interrupted.
