Gaku Yashiro presents himself as a beloved and dependable elementary school teacher, someone who appeared to stand by protagonist Satoru Fujinuma during his most vulnerable moments. Yet this wholesome image is nothing more than an elaborate facade — in truth, he is the cold-blooded perpetrator behind multiple child abduction and murder cases, using violence as a means to fill the void within himself. After his attempt on Satoru's life ends in failure, he becomes obsessively fixated on the one person who ever truly saw through him, setting the stage for a fateful confrontation that spans fifteen haunting years.
