Gaku is Satoru's homeroom teacher during primary school.

In the third Revival, while Satoru is unaware of Yashiro's true identity as the murderer, he completely renders Yashiro's plans useless. Yashiro attempts to murder Satoru by drowning him in a car in which he is locked in tight by a seatbelt. Satoru somehow survives, and Yashiro is left entertained about Satoru's persistence. Satoru goes into a coma for 15 years, and Yashiro watches over him until he wakes up again. Upon Satoru's awakening, Yashiro again tries to frame Satoru for murder, only to be caught by a plan formulated by Satoru.!~
