It's funny how the more they show Mirage and Hayate acting platonic, the harder I ship them. Like seriously, Freyja is the only one showing any romantic interest in the main triangle, but I'm just adoring how Mirage and Hayate just go on about their daily lives together as best buddies. XD
Needs more Arad though. Looks like Kaname is really into Messer... but not if Keith has anything to say to it! Messer the only one able to arouse Keith's rune has doujin written all over it.
As for the idol part of the show, I loved their poses when they started singing this show's song. As for the actual singing, Junna won this round, sorry Freyja. Well at least your singing still is better than Kaname's, which IMO was just uninspiring (like WTF Messer, this is the voice that saved you? lol)
