Rei: Dice Killing Chapter (Part 2)

Rika finally makes contact with Hanyuu, who tells her that for her to return to her old world, she must find and dispose of a piece from her old world that prevents Hanyuu from entering this new world, which in turn prevents Rika from reincarnating—if this piece turns out to be a person, for instance, she must kill that person. She is initially eager to find the item and return to her old world, especially when she responds to Satoko's bullying by assaulting her. Shortly afterward, however, Rika experiences what life with a mother is like, and begins building a new friendship with Mion, Rena, and Satoshi, as well as making peace with Satoko. Rika now feels it's all a matter of deciding which world she would rather like to stay in until she learns that her mother, now the reincarnation of Oyashiro instead of Rika, is the item she must dispose of.
