A Drama CD adapting the “Good Loser Kumagawa” Medaka Box Spinoff One-Shot manga that ran in the Winter 2012 issue of Jump NEXT.
The story takes place at Suisou Academy 2 months prior to Kumagawa’s enrollment at Hakoniwa Academy and shows events leading up to the shutdown of the Academy.
Good Loser Kumagawa was later bundled into the 15th manga volume of its parent series, Medaka Box. It can be read in English here: https://mangadex.org/chapter/d1863a4e-13ce-406f-b04e-401437db06a0/4
The ideal experience of this CD is probably had if you listen to it and read the One-shot at the same time. There’re some added lines here and there, but it’s overall the same.
Currently In the process of slowly adding captions to this vid, but don’t hold your breath on that

This CD was bundled in with the blu-ray for the first season of Medaka Box’s anime,
and just like they did in the second season of the series, Megumi Ogata plays Kumagawa.
The soundtrack for this CD is also lifted from the anime.
The track that begins at 14:00 is Kumagawa’s character theme: 僕は悪くない(Boku Wa Warukanai/It’s not my fault), and can be listened to here: https://youtu.be/cd0emTVtZpw

‘Good Loser Kumagawa’ eventually expanded into its own spinoff series through sequel light novels (https://polaristranslations.tumblr.com/kumagawa), an episode of the anime (https://youtu.be/o5V54teC17c), and a second One-Shot taking place near the end of the main series (https://mangadex.org/chapter/c590c63c-d1e1-41b0-b5ae-3f524454636f).
