I have 5, when i get more money I'll buy a few more
When I was still collecting manga, I had roughly 60 volumes (all of Fruits Basket and the two Read or Die manga titles; most of Kare Kano; and random volumes for Ouran Host Club and Azumanga Daioh). Stopped collecting a few years ago and sold my whole collection off since I started caring more for anime than manga.
There is seemingly no 'perfect' way to truly say goodbye. So I gathered a bunch of them!
