Bad assumption. Old enough to be living on my own (master's degree), but serious illness so I'm living at my parents. If by some chance I got healthy again and can survive living on my own I would still like a bookshelf with all my anime/manga in my room... no need to keep it hidden, I'm not ashamed of liking anime.
How old are you? I'm going to assume that since you keep refering to "your room", you still live with your parents which hopefully means you're still a teenager. If so, then that'll probably change once you get older, move out and have a place of your own.
The only things that are around in my apartment are the Fallout bobblehead, the Mario statue thing that was free with this year's platinum club members and a few game CEs. The majority of my games are locked up in a cabinet and all of my anime is closed off in a closet. My manga is on a bookcase in my bedroom so most people don't see that either.
When I was healthy enough to live on my own my anime collection was still too small to need storage (funny how much anime you collect when you can't leave your room). Bah, this turned into a bummer post, sorry about that.
Anyway I think I'm going to try Kiddy Grade next. Also I'm about 20 episodes into Law of Ueki, so far it is mindless but fun.
