This is "Wonderland Inside the Walls" by Jin Sakahara. I received this as a gift, but haven't had a chance to read it, so I'm putting it up for sale. It has the obi (paper band) and is in good condition, but as shown in the last photo, there is a slight scratch on the cover. It's not very noticeable, but please refrain from purchasing if you are overly concerned about condition.
