XBlaze Code: Embryo is a visual novel set 200 years before the events of BlazBlue.
As a curry-obsessed individual, I'm already identifying with the folks that want to kill the teen lead. Xblaze touches on BlazBlue mythos, but is a standalone tale, so if fighters aren't your bag, but visual novels are, you won't be too lost.
Unlike a lot of visual novels, Xblaze, which will be translated into English with Japanese audio, also presents less static images and is "more akin to an animated feature." It's coming to PS3 and Vita on June 24 for $40 and will be available both in physical form and downloadable form.
