Clock Zero ~Shuuen no Ichibyou~ the otome game is getting a live-action theatre show/adaptation （舞台化＝theatre-fied） [Official Site] EDIT: so is another game called Toki no Kizuna [vndb.org].
There is another one called Hanayaka Nari, Waga Ichizoku [vndb.org] [more info] that got a theatre show earlier this year.
I actually own a copy of Clock Zero but have not gotten around to playing it yet XD. It’s only available on PS2 or PSP I believe and it was first released in 2010.
Some screenshots from Clock Zero: 
please anyone translate this game in english pleeeeeeeeeeeeeeeease >>> i really love this game >_<"
Right, I’ve been waiting this game to be translated into english for almost 3 years..! T^T
Besides, I’ve played Hakuoki finally, after 4 years waiting, though hhehe..
Perhaps we can start a translation project for this game? If anyone knows how to extract scripts, we can set up a translation wiki for anyone to translate if they know the language. I really want to be able to play this game too 😛
