[Machine Translation] During the year-end and New Year's holidays, the frequent occurrence of mahjong house vandalism plagued the Yondaime. For some reason, I was sent out to play mahjong and met a strange man at the mahjong house. Genichiro Hinamura - the father of the fourth generation! Behind the tense game between father and son, a number of seemingly unrelated incidents, including the mahjong-so vandalism, are connected, and eventually, the nightmare of a year ago comes back to life. Alice, Tetsu and Yondaime, and even Ayaka are driven by the red nightmare's remnants.
