Well....there is hacked/patched version that has Japanese voice. They replace the dub by the original voice, so I'm actually in love with Fuuka XD. Also, her seiyuu is Noto Mamiko, which is Tsukamoto Yakumo's seiyuu
.
Note: In order to play that, your PS2 chip must be modded. I, for once, feel grateful that my PS2 is modded ^^.
I also have one question....can you date Aegis?
