Ohh that was a pretty nice performance, the set was pretty weak for it being Utaban though. The choreography was pretty nice, a nice balance of funk, pop, and some hip-hop-ish stuff. Best dance for a single since Irojire. My only problem with it was that some of them looked kinda awkward doing some of it, especially the bad dancers like sayu. But even Reina looked weird in some parts and she's usually pretty sharp at dancing.
Still dling the talk segment... It kinda dissappoints me that they have to have other guest come along with them whenever they're on the show :/
