1st off... That's Aya Hirano?
... I agree on the good voice acting, but the idea of stalkers has become questionable now.
2ndly, skimming through this thread kinda ticked me off.
Japanese girls are not too different than girls of the rest of the world. Their culture may influence them to be a bit more flirtatious and cute, but they're still human... they vary from the norm in ways.
Speaking from experience, any activity seen as its sole purpose is for the attraction of girls is otherwise known as "nanpa" and makes you look cheap and dirty. Japan is very much a "If you want chicks, pretend you don't" society, not that the rest of the world isn't that way either.
Regardless, if you just treat them as people and not try to treat them as a special organism of fascination then they will enjoy their time with you. Which will then lead to good times... I've made this mistake far too many times to conclude otherwise.
Gannbatte!
