Following a convoluted thinking process about natto being made with fermented beans, Baka eats a loaf of 3-years-old bread. Kohaku Hisui asks the girls to befriend her older-twin-sister Kujyo 'Majo' Hisui, who has morbid tastes and poor social skills, and is in their class but rarely goes to school. Yamai thinks Majo is suspicious and becomes affraid of her. Majo befriends Loli after bumping into each other at the movies. At school Majo makes a lottery-game to predict how someone will die. Later she watches an horror movie with Loli. Robo makes a reincarnation-lottery-game for Baka.
