actually she did used to smile if you've read the manga "Innocent Soul", she even had a friend named ret. And his little sister Io, but it turns out Io and Ret were just part of a repeating phantom city that a killer named Jack created to be able to kill people all the time, when brs- no sorry. 'rock' as she called herself in the manga. (YEAH SHE SPEAKS IN THE MANGA) finds out about this she kills Jack and sets Io and Ret's souls free to move on to the next life. Ret tells rock before he dies that him and Io had a lot of fun being with her, After this Ron (In the manga he is a snake like creature that follows rock and eventually turns human), hears rock questioning "fun" to herself and asks what she meant. I stopped reading shortly after this due to my emotions getting the better of me but I saw her say "nothing" and then seemingly go mute when Dead Master makes an appearance in the manga. again I stopped reading after this point so I could be wrong
The first time I've EVER heard of Black Rock Shooter, was at the end of a promo music video (with a performance and song of the same name playing beforehand) for Hatsune Miku: Project Diva F. Has this sort of anime and manga not reached the United States yet, or am I losing touch with what's been happening in recent years?
The OVA (which is only one episode) you can find dubs of on youtube. but its sliced into parts, the tv animation however you have to find it in the internet somewhere (which isn't hard. I did it) but it is in Japanese (thankfully theres subs. idk if you like subbed anime though so), and if you want to read the manga. you can just go to probably any manga reader site online and search "Black rock shooter Innocent soul"
English-subbed anime's alright with me; without at least subtitles, I tend to get lost in translation, especially since Japanese isn't my first language. Not that I don't want to learn it, but my budget (and my brain's memory capabilities, which are lousy, BTW) prevent me from doing so. T_T
