Theme Song to NTV Pro Baseball 2012 broadcast.
Few weeks ago, there are rumors of an upcoming single titled [Say Now The Your Tomorrow] -> w/c sounds weird & doesn't really make any sense, so doubting it's the real title.
But a new single?, Highly likely.
Though "Spirit" could be a B-side like Diamond & a bunch of their other songs that are previewed early (also, not used to Maru singing the opening lines)
credits 1, 2
it feels like Kame just got over puberty & his voice changed/ got deeper in recent songs..
