Réso (れそたくちら) - See if We Can Cross the Sky (空を駆ける光)

Close your eyes. You'll see the sky. Blue sky, yellow sky, orange sky, green sky, whatever colour it is. You might've wished if you could fly, but here, you can. Just step forwards, and let your soul go along the tide — the tide of THE BEAM. Let's 'See if We Can Cross the Sky'.
