The teacher was a right royal prick, telling the kid his blood was tainted, he was a mutt, and it would be better for everyone if the kid just killed himself. And everyday the student went to class, the teacher would ask why he was still alive.
2.2 million yen is a pathetically small amount, considering lawers from all over the country band together to stick up for this poor kid.
Hits close to home too, since I'm a westerner in Japan with a Japanese wife. If my future kid was every treated like that, I would want his fuckin' head.
