Gaku Yashiro

Gaku has a pretty wild backstory for a primary school teacher. He’s Satoru's homeroom guy, but things get dark fast. In a twisted timeline, this guy, Yashiro, turns out to be a murderer, having taken the lives of some innocent kids. After hanging up his teaching hat, he stepped into politics, taking his father-in-law's spot as a council member. But what a shocker—Satoru's mom, Sachiko, catches him trying to snatch another kid. She doesn’t make it out, and poor Satoru gets falsely accused. Later, Yashiro tries to take out Satoru for good, but that kid's got some serious resilience!
