This CD is part of the limited edition School Days DVD OVA Special, Magical Heart Kokoro-chan. It contains two radio sessions recorded in "Tora no Ana Cafe with Cat" for School Days.
It's definitely different from their regular radio episodes and inserted messages from Sekai and Kotonoha work well to "spice up" the mood.
I couldn't find track titles anywhere, so I made them up.
Flip side of most of the items, plus application form to send in for a copy of the last episode scenario.
