Jun is a recluse who likes to order junk from the internet and return it before the grace period expires. When he orders a strange doll, he discovers that he cannot return her and is taken on a strange journey.

This is pretty cool manga. I was expecting it to be a bit childish as it's rated T13+, but I thought the style was quite mature and it touches on some not-so-angsty teen issues. Except now I'm going to have to find Volume 2.
