Well, not doujin, but I did go to bookoff and buy a bunch of Higurashi and Umineko manga. And then I bought some really dumb shoujo off the 105 yen shelves for reading practice, hahaha! And also a light novel for little kids, since that also had furigana. So I bought like... 14 books in total |D

What I spent the most on was actually clothing. I went to takeshita dori in Harajuku at least three or four times.
