When Sensei woke up one morning, the last thing he was expecting was a call from Rin. Even less so about an urgent, secretive topic. Little did he know it would be just the first step in unravelling an insidious mystery looming over Kivotos, and the ones behind it.

Being a teacher means having students to teach, to guide towards the future. As flawed as he was, that was what he was used to. A trip to the ruins near Millennium hasn't changed that, but now he has to raise a robot who looks like a young girl into becoming human. He'd usually have somewhere to start, but what's a teacher to do for a 'student' like this?
