"Sensei to Tsumi" (Teacher and Sin) by Kuwagaki Ayu Price: 850 yen (tax included) I am selling this as I have read it once. I think it's in relatively good condition as I've only read it once. Shipping will be via post-in size. There may be changes between anonymous delivery options, such as Rakuraku (Yamato Transport) and Yuuyu (Japan Post). I hope you will consider it.
