When I opened the site just now, I was thinking "I'm surprised I haven't seen anything Love Live X Idolm@sater". Then I saw this and thought "Close enough".
LOL this is really funny. Props to Yui.. mistaking Muse as Aikatsu lol.
@Revey: with Idolmaster I think it might be too serious. Both K-ON and Love live have some thing to laugh about in the show. I didn't think I laughed during any episode of idolmaster though.
