Zero Hour

"Zero Hour" is a musical composition by Tsuyoshi Sekito that appears in Kingdom Hearts III. It has two variations, titled "Zero Hour -The Chase-" and "Zero Hour -The Rescue-".

Development
"Zero Hour -The Rescue-" is based on a composition by Yasuhiro Yamanaka from the 2011 Final Fantasy spinoff mobile game . The pieces are nearly identical in melody and structure, although the original has more electronic instrumentation and lacks an introduction. However, the Kingdom Hearts - III, II.8, Unchained χ & Union χ [Cross] - Original Soundtrack does not list Yasuhiro Yamanaka as a composer or collaborator of any kind.

Appearances
"Zero Hour" is used during events and cutscenes that possess a sense of urgency.

Composition
"Zero Hour -The Chase-" is three minutes and eighteen seconds long, while "Zero Hour -The Rescue-" is three minutes and thirty seconds long.
