Radio Show

Throughout and after the anime series ended, there was an Internet radio show on the Oreimo anime page. The hosts were Kirino/ Taketatsu Ayana and Kuroneko/Hanazawa Kana. The radio show would begin with a little skit between Kirino and Kuroneko. Then the rest of the show would be the seiyuu talking about various otaku things. For Internet radio shows, they were quite lengthy, running from 30-50 minutes. Towards the end, there were guest seiyuu who were other characters from the show.
