Haruna told me about it a while ago, meaning that she will contribute to the family income once her salary comes in after the release of the OVA episodes. :D
Although I don't have a copy of the image I saw, Riko is supposedly featured, though his/her presence could possibly be a tease towards anime fans.
Whaaat.....!!! Riko featured..!!
thanks for the info gambler coz' you just gave me a reason to wait for the OVA
