My impression of the song and MV are... it's not one of my favorites, but I don't hate it either. Maybe it will catch on with me more the more I listen to it
I wouldn't mind at all if Yuno Ohara joined TGS! I have strong doubts that will happen though... but you never know.
Also, about that fan everyone was talking about. Yeah... that guy is particularly weird, and someone I don't like. I see him at pretty much every TGS event I go to. I saw him yesterday at the release event in Tachikawa as well.
It's too bad I wasn't at the event where he did that, because I would have clocked him upside the head
Not all the TGS fans are like that though. In fact, the vast, vast majority are extremely nice, polite, and easy to get along with. I've made friends with most of the "core group" that go to all the events/concerts/lives/etc over my 6 or so years going to TGS events.
