I was wondering what your manga collections look like.
What series do you have? How many tankoubon do you have? Any merchandise? All that sorts of things.
I, myself, have not a big collection of tankoubon, since I am a student, I don't really have a lot of money to spend on manga, sadly. If I would have enough money, I would get all tankoubon of Detective Conan, since that is my absolute favorite manga. I already have a few of them, but not even close to all.
I also have some manga magazines, which I bought, while I was in Japan. Of course they are in Japanese and so I can't really read them, but a Weekly Shounen Jump was just a must buy, while I was there.
I don't really have any merchandise, except a little Gundam figure, which I once got from a Japanese friend.
As you can see, I only have a very small collection, even though I am a manga fan for a long time, but that is all due to the shortage of money, which you have as a high school student and then university student.
I guess, my collection will grow rapidly, when I got a solid job or a frequent income, which is high enough for living and those things...^^
