Fate/Extra games are popping up all over the place right now, with the Vita title in the chart, and this PSP CCC title on the way. This clip I guess introduces Jinako who is yammering away and going about her day.
The Imageepoch game is due out in Japan next spring. Mor info on it at the TypeMoon wiki. Which doesn't answer my question of "does CCC stand for cleavage, cleavage, cleavage?"
