This CD is part of the limited edition School Days DVD Volume 4. This episode features two guests, Hirakawa Daisuke (voice of Itou Makoto), and Matsumoto Yoshirou (voice of Sawanaga Taisuke).
I think it's really funny how Hirakawa-san gets all the bad rep(utation) for his role as Makoto. Sound director tells him to cast off all goodness when acting out Makoto (mentioned in previous radio appearance), and everyone gave up on even pointing out what a terrible person he (Makoto) is. I hope this role doesn't have a lasting effect on his life.
Again, I couldn't find track titles anywhere, so I made them up.
