Hozuki's Coolheadedness volume 7

What more is there is to say about the main character's sadistic tendencies? We've got Lurio the pheasant, the most humble of Momotaro's companions; Oiwa the lantern from the Yotsuya Kaidan, who hasn't appeared since volume two; Kama, the designer, who appears...surprisingly often; and even Hageito of the Records Section, who briefly appeared at the end of the last book. Volume seven's all about side-characters, and they're here to shine!
