My little manga collection 
. I'm very proud of it. I started collecting manga when I was 16. I was happy. In my collection I have mangas from many authors. My favorite is CLAMP. I have also more like 20 BL manga. My favorite author is Kou Yoneda.
I don't know if you know serie : "Hi Michael" with ginger cat. It takes me few months to collect all serie.
Everything is in polish language except TRC and one book of TB.
