Since each episode of Den-o with the denliner opening is a different version of the opening, I gotta say I like the song but not the Ura or the Kin versions of it... ii ne ii ne sugoi ne and ii yan ii yan sugoi yan feel off rhythm or tone or something that doesn't help me. But it's cool to see the variation.
Zero form is still impressive though it does what it does... Can't wait to understand more of the series as TV-N catches up!
