Kaze ni Naru (Become the Wind)

[Proginoskes]

I'd be very surprised if it hasn't been suggested before, but Doug understands Japanese, right? Then how 'bout the themesong to The Cat Returns? Kaze ni Naru (Become the Wind) (lyrics and translation) allows Doug and one other person he cares about to become a kind of wind spirit: invisible and intangible, but detectable by the gentle breezes about their persons even when they stand stock-still. In this state, Doug and guest have all the capabilities and limitations of natural winds.
