I find it interesting that you say the video is cute and call it a hyper song. It might be fast, paced but the actual meaning is quite pessimistic (Len's part primarily) and actually somewhat depressing in a way.
This is a really well drawn picture but I feel like it's missing the real mood of the song.
I'd say the main point I take from the song is that all the things that are supposed to make people happy, seem pointless. One translated version says "If I see what I should see, then is that happy? I don't understand what should be understood!"
I'd say the fast pace and seemingly random lyrics are playing into the confusion of the 'singer' rather than being 'hyper'.
I think this is an amazing of the twins, and the background is really well-done too. The shading is especially good. However, I have to agree that I never really thought of the song as cheerful. ~Tamani13, would you mind expanding on your interpretation of the song's meaning? For me, the lyrics are almost as cryptic as Hachi songs, and I haven't been able to find a clear explanation anywhere.
P.S. I am in love with your signature. Using "desu" incorrectly is far from inconceivable.
I think part of the charm of Wowaka's songs is that the meaning is so easy to interpret based on the listener. The problem is people who can't find the point unless they're slapped in the face with it. Upbeat tempo? Must be a happy song.
I looked up various translations to get a better idea of the song and I certainly thing every person could get something different so there's no real clear explanation except from the one who wrote the lyrics themselves.
What I personally take from the song may be influenced heavily by my own experiences, but that's what I like about the song. The point in the song that stood out to me most was the fact that the singer appears to be lost between what society thinks should make them happy and what really would. I think it's somewhat common for people to fall into a pattern of what they are supposed to see as 'happy' or 'lucky' but in this case they simply feel confused and distraught because they don't understand 'what should be understood'. They feel like they're trapped in an endless loop of the same boring things and it's driving them a little crazy. There's also a theme of bearing down on oneself for past mistakes.
The first half of the song sounds more confused and lost where as the second half where it switches to Len sounds a lot more negative. One of the translations says 'I tripped, giving up on my "one more time".' and 'Bad dreams continue haunting me. Don't you dare forget the fate of the mistakes you've made.'
The thing that stands out to me most is the two verses near the end.
"How could you say that it is happy? Waking up at 4am with lost and hollow eyes. To where I'll arrive next, would it be happy there? I just wish that I wasn't so tired.
This is what it means to be happy, Falling on the asphalt without seeing the very end. Breaking and crumbling into nothing, Only the sight of you is holding me back."
He's tormented by something, he wants to find happiness but it's not where people tell him it should be and he's too tired to look any more. The theme of suicide there is pretty damn obvious in the second verse there. This translation I think was based less on trying to be exact and more on the trying to convey the meaning of the text which is why I liked it.
I think there's a lot more you could pull from the song, these are just the things that stood out most to me.
