Massacre Chapter One: Rules of the Labyrinth

Synopsis

Rika begins a new world with Hanyū, but is getting tired of seeing her friends commit the same acts that lead them to terrible mistakes, until Keiichi proves to her that people can change their fate if they want during the game tournament, like the one in Watanagashi-hen, where he gives the doll he won as a prize to Mion instead of Rena, who doesn't mind that he gave it to Mion. Rika thinks that maybe this world will be different. (Source: When They Cry Wikia)
