And the exchange in which the scene culminates, as well as being hilarious, is grin-inductively awesome due to the subject matter and the over-the-top way in which Kyousuke delivers his message:
Kyousuke's father: You were in your sister's room, using your sister's computer to play a game about doing indecent things to your sister?
Kyousuke: It was really amazing. Got a problem with that? What's wrong with a high schooler having eroge? ... Iím not throwing this away! I'll defend this to the death!
Kyousuke: Listen up, old man! I like anime and eroge with a passion! I can say that I love them! If I throw this away, I won't be me anymore! Eroge are my soul! You hear me?!
