There's a video on youtube, where Kana went to a game company, that produced the Xbox 360 game coming out in Japan called GalGun.
This is where the term heart terrorist came from. In the video, one of the producers plays, then Kana does, and she beats his score. This was last week i believe.
Anyways, the game is this: it's a first person shooter, in which you run around shooting school girls with "pheremones". When you shoot them, hearts float all around the screen and you get more points for shooting them in erogenous zones. Yep, "do sukebe" game. She posted about this on twitter, and the term heart terrorist came up.
Now we are off and running....
