The opening is just... like, I don't know.. "catchy" if I may rephrase it well? The way it's set up plus the song is just perfect.
Kubarayashi did a fine job as always.
As the ending, I don't really like it... you just stare at people running all along... well, of course, there's the Harem "addition" feel, but still, don't really like the ED. The song has nothing wrong with it though, not a masterpiece, but not bad either.
I still have to note a very good OST track that touched me... I often look for those (like that one piano piece or violin/strings song that makes you want to shed tears)... Will be waiting for the grimmer and more emotional parts of the anime later (if there will be those that is).
On a side note... you can already get the full version of Straight Jet (Gendou has it available). It's also up all around on Youtube. I wuv it. :3
Currently making a piano cover of the song... will see how it turns out.
P.S: I was able to find an interesting remake of Straight Jet. Sharing for fun!
Hatsune Mikuism reaches far out to IS!
double edit: Finally... think I can play Straight Jet at about 75% now.
