What do they do?

Seriously?

How do they get to him?

He's supposed to be the smart one, and yet he has no idea what to do. But then Hikaru had not been the sharpest crayon in the box and had simply made and executed decisions, for good or ill. He had wanted that ability. But it would go against everything he is.

Hikaru continues to beep. One day he gets so loud, Masaken can't even go into class. He's kicked out and only not suspended because he looks so horrified and downtrodden himself at this failure of competency. He takes to leaving it in his shoe locker, where no one can care unless they want to dig it out of one of his socks.

Then, after school one day, the toy literally flies away.
