Gaku is Satoru's homeroom teacher during primary school. In the original timeline, Yashiro successfully murdered two children at Mikoto Elementary School—Kayo Hinazuki and Hiromi Sugita—as well as another student from Izumi Primary named Aya Nakanishi. After being a school teacher, he inherited his father-in-law's constituency and became a council member in his place. During his time as a council member, he is seen by Sachiko Fujinuma during his attempt to abduct another child. After Sachiko remembers his identity, she is immediately murdered and her son, Satoru, is framed for the murder. I
