The limited edition of volume 5 comes with a drama CD.
Kagerou Scans is planning on translating and releasing this when it comes out in March of this year.
The announced seiyuu lineup is as follows:
- Daisuke Ono (notable roles: Shizuo in Durarara!!, Midorima in Kuroko no Basuke, Sebastian in Kuroshitsuji, etc.) as Shiina
- Fukuyama Jun (notable roles: Lelouch in Code Geass, Yukio in Ao no Exorcist, etc.) as Hana
Dunno if any other characters make appearances.
Should be good.
