Yup, that is Bazett. In front of Akiha is Kouma, SHIKI, and Elesia (Ciel). The one behind SHIKI is Tsukasa Shijyou; The guy behind Nanaya is Tonami Kugamine. The two girls on top of Hisui are Akira Seo and probably Souka Tsukihime with her hair untied. Behind Satsuki is Hanei Misawa. Which leads me to the the guy at the very top who might or might not be Reikan Ryuudou.
