"Massive Wonders" is the 16th single by Japanese singer Nana Mizuki.

"Massive Wonders" contains the second opening theme and insert song for the anime Magical Girl Lyrical Nanoha StrikerS.

[1] Like her previous single, "Secret Ambition", the video features two Nana egos, one being an inactive, innocent one, dressed in white clothing.

The other ego, dressed in red clothing, dances and sings.

In a high-tech setting, the white-clothed one is held captive and/or hostage by masked uniformed people as her hands are bound together and she is constantly followed and supervised by them.
