Chapter 13:
Myoue has been skipping out on the Council of Three meetings, and now he feels irritated at the fun Koto is having.
Chapter 14:
But his anger isn't really directed at her, it's at himself, and how he acted when he was still called Yakushimaru.
Chapter 15:
He takes Koto to the no-go zone on his bike, and offers her a plan.
He'd been skipping out for a long time.
Er steht schon lange etwas neben sich.
Se ha estado escapando desde hace tiempo.
Hace tiempo que se escapaba de un modo u otro.
Il a boycotté son travail 
pendant longtemps.
Ele anda faltando muito ao trabalho.
