That was FAST.
It came with the box, and a drama CD. The DVD itself is nothing special, with two episodes and some basic non-credit intro/outro extras and such.
The big selling point is the Drama CD though, because Sasahara Keiko is actually in it and is essentially the main character of the Drama CD. I am glad to see that they haven’t totally forgotten about her.
I may translate the drama CD at some point, but don’t hold your breath. I’ll at the very least try to write up a summary for it though.
